Vaccine Stockpiling, A Prudent Precaution

01/18/2021

Following the 2019 re-emergence of Ebolavirus infection in central Africa, a vaccine was developed that proved effective in controlling an outbreak in the Democratic Republic of the Congo requiring immunization of 300,000 people.

 

International health organizations headed by vaccine provider GAVI with the support of WHO and UNICEF have now stockpiled 500,000 doses of the Ervebo vaccine manufactured by MSD in Kenya.  Studies showed that the vaccine was 97 percent effective against Ebola an infection that has a fatality rate in excess of 50 percent.

The Ministry of Health in Kenya that will be responsible for maintaining the inventory of Ebola vaccine has developed a rapid response team encompassing laboratory diagnostic specialists and members with experience in logistics and delivery of vaccines.  The Ministry has a total workforce of 229 staff deployed at various points of entry into Kenya and has designated 21 Ebola specialists to be activated in the event of an outbreak that is almost inevitable.

 

The decision to maintain an inventory of vaccines and to train responders is justified by the high mortality and social disruption caused by the disease.  Selected first responders in the U.S. have received the vaccine and have developed contingency plans following the 11 cases in the U.S. in 2014 comprising seven medically evacuated personnel and four contact cases.

 

The principle of stockpiling vaccines against both human and livestock diseases should be a major consideration with the respect to exotic infections many of which have catastrophic consequences following introduction into naive populations.  Unfortunately, stockpiles cost money to acquire and to maintain and inevitably must be replenished as a result of aging.

 

The slow pace of administration of available COVID vaccine demonstrates the need for planning, distribution and administration to populations, herds and flocks.  Fortunately, in the case of livestock, they are generally concentrated on farms and in limited geographic areas facilitating administration.  Fortunately, animals and birds do not have access to the internet and do not have prejudices regarding political, religious and social concerns and are easy and available recipients. Avian Influenza H5 and H7, Foot and Mouth disease and when available African swine fever are obvious candidates with funds allocated for Foot and Mouth disease.
