The country’s first coronavirus vaccinations are now being distributed. In trials, the Pfizer vaccine was 95% effective in preventing COVID-19, and the Moderna vaccine stands at 94%, both significantly more effective than many scientists anticipated.
Both versions of the vaccine require two injections. If you get them both, your chances of getting infected with the coronavirus are likely low. But even if you get vaccinated in the near future, experts say it’ll be months until you can ditch the masks and hug everyone around you.
The main challenge? Studies of the COVID-19 vaccines only measured whether vaccinated people developed symptoms, not whether they got infected. We know that you can become infected with the coronavirus and be asymptomatic, meaning you never develop symptoms. Asymptomatic people can still spread COVID-19 to others. So we don’t know whether a vaccine prevents asymptomatic infections and if there’s still the possibility that a vaccinated person could transmit the virus without knowing it.
“The vaccine is probably the most important tool we have right now in controlling this pandemic, but it’s not perfect and it’s not a magic bullet that can end this for good right away,” says Neal Goldstein, assistant research professor of epidemiology and biostatistics at Drexel University.
We wear masks for two reasons: to protect ourselves, and to protect others. Because there’s still a chance that you could be a silent carrier even after getting vaccinated, wearing a mask, practicing social distancing and hand-washing all remain important.
