Answer:
Vaccines for COVID-19 are critical tools for helping bring the pandemic under control when combined with effective testing and existing prevention measures. With several promising vaccine candidates in the pipeline, some under review for approval and the Pfizer/BioNTech, Moderna and Oxford-AstraZeneca vaccines approved for use by a number of stringent national regulatory bodies.
The threat to children posed by COVID-19 is enormous, extending far beyond the immediate physical effects of the disease. As lockdown restrictions continue or are re-imposed, children’s access to essential health services may be seriously affected. The resulting reductions in routine healthcare coverage levels and a looming recession are threatening the health and the future of a generation of children.
Developing a safe and effective vaccine takes time, but thanks to the unprecedented investment in research and development and global cooperation, scientists have been able to develop a vaccine against COVID-19 in record time, while still maintaining robust, evidence-based and rigorous regulatory standards.
On 31 December 2020, WHO listed the Pfizer/BioNTech COVID-19 mRNA vaccine (BNT162b2) for emergency use, making it the first to receive emergency validation from WHO since the outbreak began a year earlier. The WHO Emergency Use Listing Procedure (EUL) is a risk-based procedure for assessing and listing unlicensed vaccines with the ultimate aim of expediting the availability of these products to people affected by a public health emergency.
