Pfizer COVID-19 vaccine less effective in ages 5-11: study – CTV News

Published

 on


Two doses of the Pfizer Inc. and BioNTech SE COVID-19 vaccine was protective against severe disease in children aged five to 11 during the recent Omicron variant surge, but quickly lost most of its ability to prevent infection in the age group, according to a study by New York State researchers.

The vaccine’s efficacy against infection among those children declined to 12 per cent at the end of January from 68 per cent in mid-December compared to kids who did not get vaccinated, according the study, which has not yet been peer reviewed.

For those aged 12 to 17, the vaccine’s protection against infection fell to 51 per cent in late January from 66 per cent in mid-December.

“These results highlight the potential need to study alternative vaccine dosing for children and the continued importance layered protections, including mask wearing, to prevent infection and transmission,” the researchers said.

The vaccine was around 48 per cent effective in keeping the younger age group out of the hospital, with 73 per cent efficacy against hospitalization among adolescents last month, the data showed. That was down from effectiveness of 100 per cent and 85 per cent against hospitalization for the two age groups as of mid-December.

Dr. Paul Offit, a pediatric infectious disease expert at Children’s Hospital of Philadelphia, questioned whether the data were robust enough to say that the vaccine’s efficacy had significantly declined, particularly against severe disease.

“It’s not surprising that protection against mild illness would wane,” Offit said. “We know that Omicron is somewhat immune evasive for protection against mild illness. The goal of the vaccine is to protect against severe illness – to keep children out of the hospital.”

Offit said the number of hospitalizations were too few to draw any real conclusions, and that there was little information on why the children were hospitalized. He noted that protection from previous infection among the unvaccinated might also skew the numbers.

“Natural infection can protect against serious illness,” he said.

Younger children receive a lower 10-microgram dose of the vaccine than 12- to 17-year-olds, who receive the same 30-microgram dose as adults and are eligible for a third booster shot.

Pfizer said it is studying a three-dose schedule of the vaccine in the pediatric population, noting that studies in adults suggest that “people vaccinated with three doses of a COVID-19 vaccine may have a higher degree of protection.”

Long COVID: Half of patients hospitalised have at least one symptom two years on – Australian Hospital + Healthcare Bulletin

Long COVID: Half of patients hospitalised have at least one symptom two years on

Two years on, half of a group of patients hospitalised with COVID-19 in Wuhan, China, still have at least one lingering symptom, according to a study published in The Lancet Respiratory Medicine. The study followed 1192 participants in Wuhan infected with SARS-CoV-2 during the first phase of the pandemic in 2020.

While physical and mental health generally improved over time, the study found that COVID-19 patients still tend to have poorer health and quality of life than the general population. This is especially the case for participants with long COVID, who typically still have at least one symptom including fatigue, shortness of breath and sleep difficulties two years after initially falling ill.1

The long-term health impacts of COVID-19 have remained largely unknown, as the longest follow-up studies to date have spanned around one year.2 The lack of pre-COVID-19 health status baselines and comparisons with the general population in most studies has also made it difficult to determine how well patients with COVID-19 have recovered.

Lead author Professor Bin Cao, of the China-Japan Friendship Hospital, China, said, “Our findings indicate that for a certain proportion of hospitalised COVID-19 survivors, while they may have cleared the initial infection, more than two years is needed to recover fully from COVID-19. Ongoing follow-up of COVID-19 survivors, particularly those with symptoms of long COVID, is essential to understand the longer course of the illness, as is further exploration of the benefits of rehabilitation programs for recovery. There is a clear need to provide continued support to a significant proportion of people who’ve had COVID-19, and to understand how vaccines, emerging treatments and variants affect long-term health outcomes.”3

The authors of the new study sought to analyse the long-term health outcomes of hospitalised COVID-19 survivors, as well as specific health impacts of long COVID. They evaluated the health of 1192 participants with acute COVID-19 treated at Jin Yin-tan Hospital in Wuhan, China, between 7 January and 29 May 2020, at six months, 12 months and two years.

Assessments involved a six-minute walking test, laboratory tests and questionnaires on symptoms, mental health, health-related quality of life, if they had returned to work and healthcare use after discharge. The negative effects of long COVID on quality of life, exercise capacity, mental health and healthcare use were determined by comparing participants with and without long COVID symptoms. Health outcomes at two years were determined using an age-, sex- and comorbidities-matched control group of people in the general population with no history of COVID-19 infection.

Two years after initially falling ill, patients with COVID-19 are generally in poorer health than the general population, with 31% reporting fatigue or muscle weakness and 31% reporting sleep difficulties. The proportion of non-COVID-19 participants reporting these symptoms was 5% and 14%, respectively.

COVID-19 patients were also more likely to report a number of other symptoms including joint pain, palpitations, dizziness and headaches. In quality of life questionnaires, COVID-19 patients also more often reported pain or discomfort (23%) and anxiety or depression (12%) than non-COVID-19 participants (5% and 5%, respectively).

Around half of study participants had symptoms of long COVID at two years, and reported lower quality of life than those without long COVID. In mental health questionnaires, 35% reported pain or discomfort and 19% reported anxiety or depression. The proportion of COVID-19 patients without long COVID reporting these symptoms was 10% and 4% at two years, respectively. Long COVID participants also more often reported problems with their mobility (5%) or activity levels (4%) than those without long COVID (1% and 2%, respectively).

The authors acknowledged limitations to their study, such as moderate response rate; slightly increased proportion of participants who received oxygen; it was a single centre study from early in the pandemic.

2SLGBTQ+ lobby group head speaks on the trauma of conversion therapy

Published

 on

Although conversion therapy has now been outlawed in Canada, many are still victims causing them to go through a lot of trauma in the process.

According to Jordan Sullivan, Project Coordinator of Conversion Therapy Survivors Support and Survivors of Sexual Orientation and Gender Identity and Expression Change Efforts (SOGIECE), survivors of conversion therapy identify the need for a variety of supports including education and increased awareness about SOGIECE and conversion practices.

Also needed is access to affirming therapists experienced with SOGIECE, trauma (including religious trauma), safe spaces and networks, and access to affirming healthcare practitioners who are aware of conversion therapy or SOGIECE and equipped to support survivors.

“In January of 2021 when I was asked to be the project coordinator, I was hesitant because I wasn’t sure that my experience could be classified as SOGIECE or conversion therapy. I never attended a formalized conversion therapy program or camp run by a religious organization. Healthcare practitioners misdiagnosed me or refused me access to care.

In reality, I spent 27 years internalizing conversion therapy practices through prayer, the study of religious texts, disassociation from my body, and suppression or denial of my sexual and gender identities. I spent six years in counselling and change attempts using conversion therapy practices. I came out as a lesbian at age 33, and as a Trans man at age 51. I am now 61 and Queerly Heterosexual, but I spent decades of my life hiding in shame and fear and struggled with suicidal ideation until my mid-30s.

At times I wanted to crawl away and hide, be distracted by anything that silenced the emptiness, the pain, the wounds deep inside. I realized that in some ways, I am still more comfortable in shame, silence, and disassociation, than in any other way of being and living, but I was also filled with wonderment at the resiliency and courage of every single one of the participants.

However, many of us did not survive, choosing to end the pain and shame through suicide. Many of us are still victims in one way or another, still silenced by the shame, still afraid of being seen as we are. Still, many of us are survivors, and while it has not been an easy road, many of us are thrivers too,” said Jordan.

In addition, Jordan said conversion practices and programs are not easily defined or identified, and often capture only a fragment of pressures and messages that could be considered SOGIECE.
