People who’ve had COVID-19 may only need 1 vaccine dose, study says

CDC say people should get vaccinated even if they’d had coronavirus

Drivers with a vaccine appointment enter a mega COVID-19 vaccination site set up in the parking lot of Dodger Stadium in Los Angeles Saturday, Jan. 30, 2021. One of the largest vaccination sites in the country was temporarily shut down Saturday because dozen of protesters blocked the entrance, stalling hundreds of motorists who had been waiting in line for hours, the Los Angeles Times reported. The Los Angeles Fire Department shut the entrance to the vaccination center at Dodger Stadium about 2 p.m. as a precaution, officials told the newspaper.  (AP Photo/Damian Dovarganes)

People who’ve recovered from COVID-19 might have as many antibodies after one vaccine dose as others who’ve taken both.

A study out Monday is based on 109 people, 41 of whom had been infected.

Researchers found the participants who had never been infected developed antibodies more slowly than those who had recovered from it.

The study is not peer reviewed and it does not prove varying levels of protection.

The CDC says people should get vaccinated even if they’ve had COVID-19.
