Covid booster shots rollout prepared for third wave Top Story May 6, 2021 LONDON: Ministers, health chiefs and government scientists are stepping up preparations for an autumn booster vaccination campaign to protect against a third wave of coronavirus. Vaccines minister Nadhim Zahawi said scientists are looking at a range of options, including new jabs to protect against variants or mixing the types of injections given, so if a patient had AstraZeneca for their initial doses they could be given Pfizer as a booster. “We want them to be able, if they need to, from September onwards to boost those that are most vulnerable,” Zahawi said. The government has already ordered 60 million doses of the Pfizer vaccine in preparation for a booster campaign.
