PRAGUE — The Czech Republic is expanding its vaccination program to offer a third dose of a vaccine amid rising infections.

The Health Ministry has recommended the booster shot for anyone older than 60, health workers and other vulnerable groups.

On Monday, the first 8,000 people received a text message from the authorities that they are eligible for the third shot.

They can be given it no earlier than eight months after receiving their second dose of vaccine. Those whose immune systems are compromised and others who are seriously ill can get the booster shot as soon as four weeks after the second shot.

The Pfizer and Moderna vaccine will be administered at vaccination centers in hospitals and by general practitioners as most mass vaccination centers are being closed due to falling interest.

A total of 5.9 million people have been fully vaccinated in the nation of 10.7 million. The country offers vaccination for those over 12 and they will all be eligible to receive the booster.

Daily new COVID-19 cases exceeded 500 for three straight days last week, the highest numbers since May.
