Get your vaccine shot

The COVID-19 virus is still spreading around the world. It hangs over all of us. But some good news about vaccines (疫苗) for COVID-19 is bringing us closer to ending this terrible pandemic.

On Dec 8, the UK rolled out (推出) a vaccine made by Pfizer and BioNTech. The US started its own COVID-19 vaccine rollout nationwide on Dec 14, Xinhua reported.

China will start vaccinating high-risk groups over the winter, Zeng Yixin, deputy head of the National Health Commission (NHC, 国家卫生健康委员会), said at a press conference on Dec 19.

This means that those who work in the cold-chain industry, healthcare, customs (海关), seafood markets and public transportation are among those who will receive the vaccine first. Their work puts them at higher risk of being infected (感染).

This is the first step in China's COVID-19 vaccination plan, Zeng said. As more vaccines are approved (批准) and produced, elderly people, people with underlying conditions (基础疾病) and the general public will receive vaccines in an orderly manner.

China's COVID-19 vaccines can offer effective protection for at least six months, Zeng pointed out. Vaccination experiments have shown that the vaccines are safe and effective.

As for those who are not among the first to receive vaccines, officials at the NHC said there's no need to worry. "Wearing masks in public places, practicing social distance and washing hands are protective measures that have been proven to be very effective," said Cui Gang, a senior NHC official.
