With all the noisy disinformation that extremists have spread about the coronavirus shots, ordinary folks may not appreciate that medical historians may regard recent times as a watershed moment for vaccines as a major tool for preventing disease.
Late in 2019, public health officials welcomed a vaccine to battle Ebola, a scary hemorrhagic fever. It took scientists cooperating across three continents, combined with the threat of a major outbreak of the rare but lethal viral infection, to allow at least a wider deployment of the Ebola vaccine — and to prove that it worked.
Public health officials recently have reported success with a vaccine against another huge harm in the tropical and developing world: malaria. The chronic, debilitating, and too often deadly illness — spread by mosquitoes and a blood-borne parasite — kills 500,000 people annually, half of them children in Africa. The novel vaccine tackles a big problem in a regimen of multiple shots, attacking one of the major parasites (Plasmodium falciparum) that makes malaria such a scourge. The vaccine is imperfect. But, combined with disease-fighting programs, such as campaigns to provide poor people with low-cost mosquito netting, the relatively low-cost, easily carried out vaccination program will go far to slash malaria’s harms, experts say.
As for the advances underlying several of the prominent coronavirus shots, the innovative mRNA technology rapidly may yield progress against other illnesses. Getting the body’s own immune system to target key ways that diseases attack human cells may soon provide weapons aimed at the annual killer influenza, and, yes, certain types of cancer.
Let’s not forget that, relatively recently, researchers (in 2006) developed a vaccine that can prevent a half-dozen types of cancer, notably cervical and other female reproductive cancers, by targeting and blocking infections by the human papilloma virus (HPV). That vaccine needs wider use and acceptance in young women and men.
Caveat: Vaccines have been legend for being difficult to develop. Despite decades of intensive research around the globe and the spending of large public and private sums, a safe, effective, and affordable vaccine against HIV-AIDS remains elusive.
Important reminder: Tens of millions of Americans still have not had the safe, effective, and free coronavirus shots. While all medical interventions carry risks, the benefits of vaccinations far outweigh these, especially with the contagious, debilitating, deadly coronavirus. Public health officials are pleading with the public to get shots not only against the coronavirus but also the flu — to prevent already overwhelmed health systems from collapse in a “twindemic.” Patients should talk to their doctors to ensure they and their loved ones are up-to-date with the range of vaccines that can safeguard them from illness.
