Millions of Covid vaccinations needed before any side-effects are known

When it comes to Covid-19 vaccines clinical trials are important in providing vital information says a paper written by the UK’s Department of Health & Social Care (DHSC).

The UK Covid-19 Vaccines Delivery Plan was published on 21 January 2021 and sections 4.10 and 4.11 are compelling reading.

Section 4.11 says: “As with all new medicines, we will monitor the vaccine’s effectiveness and safety to ensure we track and understand if any exceptionally rare side effects exist.

“As with all vaccination programmes, exceptionally rare side effects may not be apparent until millions of people worldwide have received the vaccine.”

The report also says (3.1) that vaccine development and delivery…[have] no guarantee of success.

“Vaccine candidates typically have a high rate of failure during their clinical trials, and no vaccines have yet been developed for some diseases such as HIV.”

The report says it will only be after significant numbers of people have been vaccinated that the DHSC will have more complete information on extra benefits such as preventing hospitalisation, severe disease and reducing transmission.
