Amid the global pandemic, there is light at the end of the tunnel. Vaccines for COVID-19 are now available. They were developed in record time – one of the greatest success stories of modern science.

Instead of using weakened or inactivated components of the virus to activate the body’s immune response, these new vaccines use Messenger RNA or “mRNA”.
