Vaccinating the World's population every year with MMR, Rabies, Adenovirus 2 and Adenovirus 7 vaccines will protect it from threats of emerging pandemics caused by the following viruses: Ebola virus, Marburg virus, Chapare virus, Australian and European Bat Lyssavirus, Chandipura virus, Sin nombre and Bayou viruses, Hendra virus, Nipah virus, Louping ill virus and Avian influenza virus. This is because these vaccines show significant cross-reactivity with the above 10 viruses- which arre the most likely to jump species (from animals to humans) and cause a pandemic. The MMR, Rabies, Adenovirus 2 and 7 vaccines are already approved and can be easily administered en-masse'.
This simple policy of continuing vaccination with these already approved vaccines for the adult and ageing population may ensure protection against future viral pandemics. This approach is significantly better than a retroactive emergency response once the pandemic has already begun (as was the case with COVID-19).
