But the immune cells that vaccination spurs do last a long time.
Merck announced preliminary data suggesting the drug reduced the risk of hospitalisation and death by 50%.
Vaccine donations are unsustainable and often inefficient to scale. They are a temporary solution to a systemic issue.
The risk of COVID-19 exposure from high-touch surfaces within grocery stores is low if physical distancing guidelines and recommended cleaning protocols are followed.
A growing body of research shows that nutrition, sleep, exercise and a host of other lifestyle choices can help optimize the immune system. But they are no substitute for life-saving vaccines.
Making vaccines in South Africa by building on the foundation that’s been laid is possible. But only if substantial and sustained investment in human resources and infrastructure becomes a reality.
It’s more evidence a lab leak is very unlikely.
The core of the objections, whether they are about vaccinations, lockdowns, social distancing, or mask wearing, seems to concern an apparent erosion of personal liberty.
An FDA panel has voted against recommending approval of a booster COVID-19 shot for the general population – disappointing some public health officials.
Before the pandemic, the public perceived science as infallible and inaccessible. But the opening up of research to the general public has changed that perception.
Two different respiratory viruses were found to swap proteins when they infected the same cell.
When the coronavirus copies itself, there is a chance its RNA will mutate. But new variants must jump from one host to another, and the more infections there are, the better chance this will happen.
The next months are going to remain difficult. But I’m still hopeful about the future. There will come a point when enough people are vaccinated that case numbers begin to decrease.
A medical student answers questions he gets asked at a COVID-19 vaccine clinic: Efficacy versus real-world effectiveness, immune response and how the mRNA vaccines compare to vaccines already in wide use.
Cell-mediated immunity is particularly effective at eradicating viruses, and more durable. This is important in the fight against COVID-19.
It’s not spreading widely, and it’s not at Australia’s doorstep. The tools we have in place work against the coronavirus.
There are practical things you can do to make your child more comfortable if they’re ill.
An infectious disease doctor explains the science behind COVID-19 vaccines at a level that children – and adults – of all ages can understand.
