(This is not an uncommon process for vaccines that need a strain update, much like the annual flu shot.) Health officials approached the approvals for the retooled omicron boosters, also known as bivalent vaccines, a bit differently this time around, since clinical trials testing the BA.4- and BA.5-specific shots were still happening at the time of their authorization. Here’s what to expect if you go in for the jab. Still, some people have questions about the new omicron boosters, including the side effects they can cause. Children as young as 6 months old are also eligible for an updated booster if they were vaccinated with Moderna. We need more work to understand why this is the case and what can be done to help.Health officials are recommending that fully vaccinated individuals 5 years and older roll up their sleeves for the added dose of protection against the illness that has taken more than 1.08 million American lives. The fact remains that two years on from their first infection, some people don't feel fully recovered and their lives continue to be impacted by the long-term effects of the coronavirus. This study shows that some individuals have measurable changes in these tests after COVID-19 going on for nearly two years. "We used sensitive tests to measure speed and accuracy across a range of brain challenges. Professor Claire Steves, a Professor of Ageing and Health at King's College London, added: This study shows the need to monitor those people whose brain function is most affected by COVID-19, to see how their cognitive symptoms continue to develop and provide support towards recovery." "However, the result that COVID had no effect on performance in our tests for people who felt fully recovered, even if they'd had symptoms for several months and could be considered as experiencing 'long COVID', was good news.
"Our findings suggest that, for people who were living with long-term symptoms after having COVID-19, the effects of the coronavirus on mental processes such as the ability to recall words and shapes are still detectable at an average of almost two years since their initial infection. Lead author Dr Nathan Cheetham, a Senior Postdoctoral Data Scientist at King's College London said: In contrast, participants who did not feel fully recovered after infection had lower task accuracy scores on average. People who felt fully recovered after COVID-19 infection performed similarly to those who had not had the virus at all. By the second round of testing, the average time since participants' initial COVID-19 infection was almost two years.ĭigging deeper into the analysis, the researchers separated participants by whether they felt fully recovered following COVID-19 infection. There was no significant improvement in these test scores between the two rounds of testing, which took place nine months apart.
In these people, the effect of COVID-19 on test accuracy was comparable in size to the effect of a 10-year increase in age.
The participants whose test scores were most affected by COVID-19 were those who had experienced symptoms related to the virus for 12 weeks or more. Data was collected for over 3,000 participants of the COVID Symptom Study Biobank study, across 12 tasks that tested memory, attention, reasoning, processing speed and motor control. Researchers from King's College London looked at whether infection with COVID-19 affected performance in two rounds of online cognitive testing that took place in 20.
