कोरोना वायरस के वैरिएंट कैसे बनते हैं ?What causes a virus to change to a new variant? WHO Series

जैसे जैसे कोरोना वायरस फैलता है ,यह अपनी रचना बदलकर नया वेरिएंट बना लेता है। वैक्सीन भी वैसे ही बदलना होगी। बेहतर बनाना होगी। अभी जो वैक्सीन हैं वे काफी वेरिएंट कवर कर लेंगी। आगे रिसर्च मदद करेगी.

When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes.The COVID-19 vaccines that are currently in development or have been approved are expected to provide at least some protection against new virus variants because these vaccines elicit a broad immune response involving a range of antibodies and cells. Therefore, changes or mutations in the virus should not make vaccines completely ineffective.
