EXPLAINER: What do we know about booster shots for COVID-19? – Burnaby Now

Published

 on


U.S. health officials may soon recommend COVID-19 booster shots for fully vaccinated Americans. A look at what we know about boosters and how they could help fight the coronavirus:

WHY MIGHT WE NEED BOOSTERS?

It’s common for protection from vaccines to decrease over time. A tetanus booster, for example, is recommended every 10 years.

Researchers and health officials have been monitoring the real-world performance of the COVID-19 vaccines to see how long protection lasts among vaccinated people. The vaccines authorized in the U.S. continue to offer very strong protection against severe disease and death.

But laboratory blood tests have suggested that antibodies — one of the immune system’s layers of protection — can wane over time. That doesn’t mean protection disappears, but it could mean protection is not as strong or that it could take longer for the body to fight back against an infection.

The delta variant has complicated the question of when to give boosters because it is so much more contagious and much of the data gathered about vaccine performance is from before the delta variant was widely circulating. Delta is taking off at the same time that vaccine immunity might also be waning for the first people vaccinated.

Israel is offering a booster to people over 50 who were vaccinated more than five months ago. France and Germany plan to offer boosters to some people in the fall. The European Medicines Agency said it too is reviewing data to see if booster shots are needed.

WHEN WOULD THEY BE GIVEN?

It depends on when you got your initial shots. One possibility is that health officials will recommend people get a booster roughly eight months after getting their second shot of the Pfizer or Moderna vaccine.

Officials are continuing to collect information about the one-shot Johnson & Johnson vaccine, which was authorized for use in the U.S. in late February, to determine when to recommend boosters.

WHO WOULD GET THEM?

The first people vaccinated in the United States would likely be first in line for boosters too. That means health care workers, nursing home residents and other older Americans, who were the first to be vaccinated once the shots were authorized last December.

BOOSTER? THIRD SHOT? WHAT’S THE DIFFERENCE?

Transplant recipients and other people with weakened immune systems may not have gotten enough protection from vaccines to begin with. They can now receive a third dose at least 28 days after their second shot as part of their initial series of shots needed for them to be fully vaccinated. For those with normal immune systems, boosters are given much later after full vaccination — not to establish protection, but to rev it up again.

WHAT QUESTIONS REMAIN?

Still unknown is whether people should get the same type of shot they got when first vaccinated. And the nation’s top health advisers will be looking for evidence about the safety of boosters and how well they protect against infection and severe disease.

Global access to vaccines is also important to stem the pandemic and prevent the emergence of new variants. Booster shots could crimp already tight global vaccine supplies.

WHAT ABOUT THE UNVACCINATED?

Dr. Melanie Swift, who has been leading the vaccination program at Mayo Clinic in Rochester, Minnesota, says getting more shots into people who haven’t yet been vaccinated at all is “our best tool, not only to prevent hospitalization and mortality from the delta variant, but to stop transmission.” Every infection, she says, “gives the virus more chances to mutate into who knows what the next variant could be.”

“People who took the vaccine the first time are likely to line up and get their booster,” Swift says. “But it’s not going to achieve our goals overall if all their unvaccinated neighbors are not vaccinated.”

B.C. records seven COVID-related deaths, 80% of those eligible fully vaccinated – News 1130

Published

VANCOUVER (NEWS 1130) – Seven more British Columbians have died due to COVID-19 in the past 24 hours, as Fraser Health once again recorded the most new cases in the province.

A total of 743 new infections were recorded on Friday, including 292 in Fraser Health and 177 in Interior Health. Vancouver Coastal Health recorded 111 cases and Northern Health saw 106. Island health recorded the remaining 57 cases.

Four of the latest deaths were within the Fraser Health Authority, while Interior Health, Northern Health, and Island Health recorded one each.

The Fraser Health region also has the most active cases, with 2,029 of the 5,979 province-wide.

The province says 319 COVID-19 patients are in the hospital, including 149 in the ICU.

Earlier Friday, the health ministry issued a statement, confirming all COVID-19 patients who are hospitalized are counted in the daily totals once they enter the facility, but are removed from the total even if they remain hospitalized but are no longer infectious.

“Once a patient in critical care is no longer infectious with COVID-19, the patient is removed from daily critical-care totals. However, for planning purposes, these patients are still included in the overall COVID-19 counts for the hospital,” the ministry added in a statement.

It says some patients need to stay in the hospital for “difficulties with other health conditions … that are no longer directly tied to COVID-19,” or because they may have caught the virus while in the hospital and still need care for the original issue they were admitted for.

“This means some patients who entered hospital or critical care as a COVID-19 patient may no longer be counted as COVID-19 patients once they are no longer infectious, even though they remain in hospital.”

It says as of Sept. 21, 2021, there were 152 patients in B.C. hospitals in that category. “Discontinued isolation,” which is usually over after 10 days if the patient doesn’t have a fever and their symptoms are improving.

B.C. reaches 80% mark for those with two vaccine doses

In the past day, 7,858 British Columbians aged 12 and up received their second dose of a COVID-19 vaccine, bringing the total to an even 80 per cent. Another 6,778 people received their first dose bringing that percentage up to 87.5.

According to the province, people not fully vaccinated accounted for 75 per cent of cases between Sept. 16 and Sept. 22. It also says they accounted for 81.9 per cent of hospitalizations between Sept. 9 and Sept. 22.

Rodents on the rise: How to avoid an infestation this fall

Published

 on

Rodents have become a larger problem for Canadian homeowners since the beginning of the Covid-19 pandemic. The pests that lived near bars and restaurants moved into residential neighbourhoods during lockdowns, spreading out their colonies and causing trouble.

With colder weather just around the corner, these rodents are likely to break into people’s homes. Invasions are especially common in the fall and winter when pests seek a warmer place to stay. Mice sneak in via the holes in the wall, and rats dig underground and into the basement.

While many homeowners deal with mice every year, it is important that they be kept out. Rodents are potential carriers of disease, and they will damage the home’s interior. The following tips, when used together, will help ensure that your home is pest-free this winter.

Block Entry Points

Rodents come from outside. While it may seem like they appear out of thin air, rodents find openings in the outer walls of the home and sneak their way inside. Wall vents, cracked window frames, and doors that have been left open are often to blame.

Examine your home’s exterior very carefully and use caulking or mesh to block the openings you find. Check between the layers of your siding, underneath your deck, and along the edges of your soffits for openings of 5mm or more. Put weatherstripping on the bottoms of your doors and seal cracks in the foundation with epoxy.

If you’re not sure you got them all, contact a mice exterminator for an inspection and pest-proofing service. Professionals offer complete pest-proofing in addition to pest control. They can find the entry points you missed and close them for you. If you know that there are rats in your neighbourhood, a professional can protect your foundation by digging a trench and attaching a mesh to its sides. This will prevent rats from digging into the basement.

Do Some Fall Cleaning

Spring isn’t the only time of year for cleaning. Mice, rats, ants, and other pests can smell the food you keep, and they will want their share. Deep clean the kitchen this fall and maintain it to keep pests out when it gets cold. Vacuum everywhere and clean the floors beneath your major appliances. Keep surfaces clean and store food in airtight containers to reduce odours. Never leave dirty dishes out overnight and use lidded garbage cans.

In addition to food, pests love clutter. Rodents like to hide in quiet, cluttered areas, like messy basements and storage rooms. This way, they can hide as they move from place to place. Get organized this fall and get rid of what you don’t need. Move objects off the floor and create space so there is nowhere for pests to hide.

Tidy up the Yard

Because rodents love food and clutter, it is important that you maintain the yard, as well. Trim back the vines, bushes, and plants that grow around the walls of the home to reduce the number of potential hiding spots. Move patio furniture and firewood away from the sides of the home, as well. Mow the lawn, rake the leaves, and bag all your organic materials for collection.

Pest control experts recommend getting rid of the bird feeder because it attracts rodents. While it is unfortunate, bird feeders are magnets of animal activity. Consider getting rid of it when the temperature cools or switch to one that hangs far away. Harvest your apples and home-grown produce on time, and secure your garbage cans with bungee cords or tight locks.

Police in Quebec say they are looking for a man who is alleged to have repeatedly punched a nurse in the face because he was angry she had vaccinated his wife against COVID-19.

Police say a man between the ages of 30 and 45 approached the nurse on Monday morning at a pharmacy in Sherbrooke, Que., about 150 kilometres east of Montreal.

They say he accused the nurse of vaccinating his wife against her consent and repeatedly punched the nurse before leaving the store.

Police say the nurse had to be treated in hospital for serious injuries to her face.

Quebec’s order of nurses tweeted today that the alleged assault was unacceptable and wished the nurse a full recovery.

Sherbrooke police are asking for the public’s help in finding the assailant, who they say has short dark hair, dark eyes, thick eyebrows and a tattoo resembling a cross on his hand.
