Dubai: The creation of vaccines against COVID-19 has been a bioengineering feat setting a record in research, manufacture, approvals and administration.
So far, we know that at least five active vaccinations (DNA, RNA, Viral Vector, Viral Subunit, Live attenuated, Inactivated, Virus Like Particles, Split Virus Vaccines, Ribonucleo Protein vaccine) have been created. In the passive vaccination variety, the monoclonal, polyclonal anti-bodies, the Convalescent Plasma and mRNA induced antibodies vaccine are available.
As vaccines receive approval and many have proved to have between 85-95 per cent efficacy, there is a sense of cautious optimism in the healthcare community. 90-year-old Margaret Keenan, the first patient in the UK to receive the Pfizer-BioNTech COVID-19 vaccine, administered by nurse May Parsons at University Hospital, Coventry, England, Tuesday Dec. 8, 2020.
