Amid push for third doses of COVID vaccine, some Maryland residents never got their second

With COVID-19 cases again on the rise and a new strain emerging, those in public health are urging all U.S. adults to get booster shots of the vaccine. But another group — people who never came back for their second dose — is getting less attention. At least 6.5% of the more than 4 million vaccinated Marylanders haven’t returned for the second shot of the two-dose regimen on the recommended timeline, an analysis of state data by The Baltimore Sun shows. The shots are typically scheduled three or four weeks apart, respectively, for the most widely used vaccines: Pfizer/BioNTech and Moderna.
