"Until a coronavirus vaccine is ready, pneumonia vaccines may reduce deaths from COVID-19"
HOW PNEUMOCOCCAL VACCINATION PROTECTS AGAINST COVID-19
Protection against serious COVID-19 disease by pneumococcal and Hib vaccines makes sense for several reasons. First, recent studies reveal that the majority of hospitalized COVID-19 patients, and in some studies nearly all, are infected with streptococci, which causes pneumococcal pneumonia, Hib, or other pneumonia-causing bacteria. Pneumococcal and Hib vaccinations should protect coronavirus patients from these infections and thus significantly cut the risk of serious pneumonia.
Two of these proteins found in pneumococcal vaccines mimic the spike and membrane proteins that permit the virus to infect cells. This suggests pneumococcal vaccination may prevent SARS-CoV-2 infection. Two other mimics are the nucleoprotein and replicates that control virus replication. These proteins are made after viral infection, in which case pneumococcal vaccination may control, but not prevent, SARS-CoV-2 replication.
Preventing pneumococcal and Hib complications of influenza and COVID-19, and perhaps proxy-vaccinating against SARS-CoV-2 itself, helps everyone. Administering these already available and well-tested pneumococcal and Hib vaccines to people will save money by freeing up hospital beds and ICUs. It will also improve public health by reducing the spread of multiple infections and boost the economy by nurturing a healthier population.
