Experts Explain: How do Covid-19 vaccines work, and do they help?
Covid-19 vaccine: Five days into India's mass vaccination programme, there are some concerns over vaccine hesitancy. At this crucial moment in the fight against the novel coronavirus pandemic, two of the country’s most eminent vaccine scientists weigh in on some old and new questions.
It has been five days since India began vaccination against the novel coronavirus disease. More than 7 lakh people have been given one of the two vaccines approved by the regulator. But several people, including some doctors and other healthcare workers, continue to be hesitant. This has led to concerns over ‘vaccine hesitancy’.
Vaccines are a product of science. If the scientific method and process is followed scrupulously, based on data and evidence, there should be little room for doubt. This is a good time to revisit some of the usual questions regarding vaccines, and to address fresh questions that are emerging.
