A new study led by Public Health England, a government agency, found that people who have been infected by Covid-19 may have immunity to the virus for at least five months. The findings are preliminary and have not yet been peer reviewed, but they offer some reassurance to frontline health care workers.
The researchers monitored almost 21,000 healthcare workers from across the United Kingdom between June and November and regularly tested them to see if they had been infected with Covid-19. Of those monitored, 6,614 people were found to have had the virus before and among them, 44 developed possible new infections.
There are some important caveats to note. The researchers warned that the protection was not absolute and that it was unclear how long any immunity lasts. It is also possible that those who have a degree of immunity against the virus may still be able to transmit it to others. Early insight from the next stage of the study shows that some people with existing immunity carry high levels of virus.
The science might sound complicated, but the implications for real life are not. You might be immune to the virus once you’ve recovered from Covid-19, but you should still wear a mask and practice social distancing in order to protect those around you.
YOU ASKED. WE ANSWERED
Q: How do the Covid-19 vaccines work?
A: Vaccines typically mimic part of the virus they protect against, prompting a response from the immune system. The Covid-19 shots use different approaches.
The vaccines from Moderna and Pfizer use a new technology. The vaccines deliver messenger RNA, or mRNA, which is a genetic recipe for making the spikes that sit atop the coronavirus.
AstraZeneca’s vaccine, developed with a team at Britain’s Oxford University, is called a vector vaccine. It uses a common cold virus called an adenovirus to carry the spike protein from the coronavirus into cells. Johnson & Johnson’s vaccine and Russia’s Sputnik V use a similar approach.
