MANILA, Philippines — A new report by the World Health Organization (WHO) has found that vaccines against 24 pathogens could reduce the global daily doses of antibiotics needed, thereby supporting worldwide efforts to address antimicrobial resistance (AMR).
Some of these vaccines are already available but underused, while others need to be developed as soon as possible and brought to the market.

AMR occurs when bacteria, viruses, fungi and parasites no longer respond to antimicrobial medicines, making people sicker and increasing the risk of illness, death and the spread of infections that are difficult to treat.
Article continues after this advertisementIt is driven largely by the misuse and overuse of antimicrobials, particularly antibiotics. Yet, at the same time, many people around the world do not have access to essential antimicrobials.

The pentavalent vaccines (5-in-1) provided by the Department of Health (DOH) to newborns for free, under its National Immunization Program, offer protection against diphtheria, tetanus, pertussis, hepatitis B and HiB.

“Addressing antimicrobial resistance starts with preventing infections, and vaccines are among the most powerful tools for doing that,” WHO Director General Dr. Tedros Adhanom Ghebreyesus said in a statement.
“Prevention is better than cure, and increasing access to existing vaccines and developing new ones for critical diseases, like tuberculosis, [are] critical to saving lives and turning the tide on AMR,” he added.
Hospital costsEach year, nearly 5 million deaths are associated with AMR globally, according to WHO estimates.
Vaccinated people have fewer infections and are protected against potential complications from secondary infections that may need antimicrobial medicines or require admission to hospital.
For example, vaccines against Streptococcus pneumoniae—including the pneumococcal conjugate vaccine (PCV) which the DOH-NIP offers for free to senior citizens—could save 33 million antibiotic doses.
Vaccines for tuberculosis—which are also mandatory in the Philippines for newborns—could save between 1.2 and 1.9 billion antibiotic doses.
Globally, the hospital costs of treating resistant pathogens, as evaluated in the report, are estimated at $730 billion (P42 trillion) each year.
If vaccines could be rolled out against all the evaluated pathogens, they could save a third of hospital costs associated with AMR and reduce the global daily doses of antibiotics needed by 22 percent or 2.5 billion.
Reducing fatalitiesDuring the 79th United Nations General Assembly High-Level Meeting on AMR on Sept. 26, world leaders approved a declaration committing their nations to a clear set of targets and actions by 2030—such as reducing by 10 percent the estimated 4.95 million fatalities associated with bacterial AMR.
In the Philippines, the Research Institute for Tropical Medicine recorded in 2019 alone the 15,700 deaths attributable to and 56,700 deaths associated with AMR.
To prevent its spread, the DOH discourages the public against self-medication and using antibiotics without consulting a doctor.
