Vaccines against COVID-19 are not “experimental”. This was reported 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 were subjected to standard safety tests prior to approval for use.
The standard procedure is to continue safety monitoring after full vaccine approval. Johnson & Johnson and AstraZeneca are viral vector vaccines, a type of vaccine also used during Ebola outbreaks and in disease studies, including influenza, Zika and HIV. Both use an altered and attenuated version of the harmless adenovirus to provide our cells with instructions to begin producing parts of the coronavirus protein. This will trigger an immune response and prevent infection in the future.
The COVID-19 vaccines, produced by Pfizer and Modern, generate a similar immune response using messenger RNA (mRNA). Although these are the first mRNA vaccines to be widely used, the technology behind them has been evolving for decades.
