Q: What are the risks of the newly identified coronavirus variants?
A: It’s not yet known whether mutant versions cause more severe disease, but some are likely more contagious. Scientists expect vaccines will work but are monitoring the situation.
In a tweet, Sen. Rand Paul misleadingly suggested that immunity from “[n]aturally acquired” COVID-19 was better than that from a vaccine. But it’s not known how immunity from the two sources compares — and the entire point of a vaccine is to offer immunity without the risk of getting sick.
President Trump said that once he came down with COVID-19, people for partisan reasons shifted from saying immunity was lifelong to saying it lasted only a few months. Experts haven’t changed their estimates.
