mRNA Coronavirus Vaccine , our hopes and cautions to exercise.

Pfizer and BioNTech announced with lots of positive messages today that their vaccine, a mRNA vaccine, is showing great promise.

I hope it is effective in the vulnerable groups and produces good immune memory. The efficacy and safety data has to be be externally and independently verified.

If the immune memory is long, that will also be very good news.

Going forward with increasing reports of mRNA vaccines appearing to work, the work to sort out the cold chain has to also start. These vaccines need specialist freezers, they need to keep the cold chain going at MINUS 80 degrees Centigrade.

The vulnerable people receive it first together with front line staff and thereafter other groups of people.

Best way forward is to start immunising globally, in all countries, simultaneously. This helps to reduce circulating virus globally. We are in this pandemic together and we must not leave behind the poorer countries, this is going to be a test of rich countries working in the global interests, for all of humanity.
