Vaccines against COVID-19 are not “experimental”. This was announced by the press service of the Ministry of Health. Individuals and organizations claiming that COVID-19 vaccines are “experimental” have missed animal trials and completed human clinical trials. All COVID-19 vaccines have passed standard safety tests before being approved for use.
It is standard procedure to continue safety monitoring after full vaccine approval. Johnson & Johnson and AstraZeneca vaccines are viral vector vaccines, a type of vaccine also used during Ebola outbreaks and in disease research, including influenza, Zika, and HIV. Both use a modified and weakened version of a harmless adenovirus to instruct our cells to start producing parts of coronavirus proteins. This will trigger an immune response and prevent future infection.
COVID-19 vaccines produced by Pfizer and Modern use messenger RNA (mRNA) to generate a similar immune response. While these were the first widely used mRNA vaccines, the technology behind them has been developed for several decades.
