You’ve been vaccinated; can you now safely see your friends and family? New research hints that vaccinated people may be less likely to transmit the coronavirus, but they are not 100% in the clear.

For elite athletes, even mild COVID-19 vaccine side effects can throw their training plans off course. But they can plan ahead.
We mapped the genes of B cells to better understand why some develop immunity and others don’t.
We have limited information about the reported deaths of 30 elderly people in Norway who had received the Pfizer COVID vaccine. Here’s what we do know.
Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
With a vaccine now approved in the UK, other countries won’t be far behind. But a vaccine won’t singlehandedly ensure the virus doesn’t cross international borders when travel picks up.
It’s not only shedding and reinfection which are different — there are actually two types of viral shedding.
Distributing a vaccine is a bit like boarding a plane — we can’t all board at the same time. So who gets priority? There are a few reasons we should consider vaccinating older people first.
Canada has set aside a total of 414 million doses of different types of vaccine. Some exploit known mechanisms, others are based on previously untested approaches.
Some have suggested the US allow healthy people to return to normal life, catch the coronavirus and get the population to herd immunity. The science says this plan is doomed to fail from the start.
Time changes make many people feel tired, irritable, and unable to sleep.
These drugs may help slow or reverse immune system decline.
Vaccines work by teaching your immune system about new viruses. Your immune cells are very clever – they will remember what they learnt, and protect you if you encounter that virus in the future.
Older coronavirus patients face grimmer outlooks. A virologist explains the aging-related changes in how immune systems work that are to blame.
The cold supply chain keeps vaccines fresh during distribution, but the current system is nowhere near large enough to distribute the billions of COVID-19 vaccines that the world needs.
Wearing face masks may allow a tiny number of viral particles to slip through, possibly allowing our body to gain some sort of immunity.
A few people have developed COVID-19 twice. That doesn’t mean a vaccine can’t offer long-term protection.
Senate Republicans continue to push for sweeping liability protection for companies from coronavirus-related lawsuits, but research and evidence suggests there’s little real risk.
This is just one person. Is he the exception? Is he the rule? We don’t know yet for sure. But reinfection is definitely possible.
Reports describe a Hong Kong man who was reinfected with the coronavirus after returning from Europe. Does that mean he wasn’t immune after the first infection?
