Having to prove you have been vaccinated against a disease is not new, but some oppose COVID vaccine passports.

Doctor Amir Khan explains what to expect after getting a coronavirus vaccine.

This is how the coronavirus, and the new vaccines, may affect pregnancy, breastfeeding, sperm counts and fertility.

Countries scrambling to be the first to inoculate their populations will achieve little if others go unvaccinated.

Will the new vaccines be effective against the new strains of COVID-19? The short answer is ‘probably’.

It may be even more infectious, but how dangerous is the new variant of the virus that has been identified in the UK?

While one study has come out supporting this claim, there is no substantial evidence yet that glasses can protect you.

Why has the WHO said a ‘worrying number’ of bacterial infections are becoming resistant to medicines?

While a vaccine is being developed, researchers are trialling existing drugs that could help doctors treat coronavirus.

More than 100 countries, the WHO and pharmaceutical companies are working on testing and developing a COVID-19 vaccine.
