Is it safe to visit grandparents once vaccinated against Covid-19?
The conclusion
The risks of getting sick are lower for grandparents after they have been vaccinated. But vaccination does not eliminate the risk (for grandparents or their visitors), so it’s a good idea to assess your circumstances, continue to take some precautions, and make sure everyone is comfortable with the terms of the visit.
The details
The virus that causes Covid-19 continues to mutate, increasing the chance that certain variants will make vaccines less effective. And it’s still unclear how much protection vaccines offer against transmitting the virus, so grandparents may be able to spread Covid-19 to their visitors, even if the vaccine prevents them from getting sick themselves.
