COVID-19 Vaccines

Updated on February 4, 2022

As the COVID-19 vaccines are introduced, many people have questions about their development, safety, access, cost, and other common concerns.

This section provides information about what scientists do and do not know yet about the vaccines, drawing from the World Health Organization (WHO), the Ministry of Health and Family Welfare, Government of India (MoHFW), the United States Centers for Disease Control and Prevention (CDC), and other trusted sources. Some of this language is used word for word, and other language is paraphrased. We would like to acknowledge the hard work of these organizations in compiling this information.

It is important for journalists to know what to ask and how to report on this changing information. We have provided a list of tips for reporting on COVID-19 vaccines below. By printing accurate information, the media can also minimize rumors and misinformation, helping reduce public anxiety and increase confidence in taking the vaccine.
