Medical Experts Urge Maternal Vaccination as RSV Threatens Taiwan's Newborns

With Taiwan's birth rate ranking among the lowest in the world, safeguarding the health of every newborn has become a critical national priority. Leading medical experts are now sounding the alarm over respiratory syncytial virus (RSV), warning that it remains a leading—and frequently underestimated—cause of infant mortality.

Huang Chien-pei (黃建霈), secretary-general of the Taiwan Association of Obstetrics and Gynecology, noted that Taiwan's maternal and neonatal mortality rates currently rank near the bottom among member states of the Organisation for Economic Co-operation and Development (OECD). This disparity, Huang said, highlights a pressing need to improve the island's maternal and infant healthcare infrastructure.

The Severe Toll of RSV on Infants

Hsu Kuang-pin(許廣鑌), director of a private maternity and children's hospital, emphasized that RSV is a leading cause of hospitalization and death among infants globally.

In Taiwan, the virus takes a heavy toll on the youngest and most vulnerable patients. According to Hsu, the data reveal a stark contrast between RSV and other common respiratory viruses:

Approximately 1,000 infants are hospitalized due to RSV in Taiwan each year, with one in four requiring admission to the ICU. For newborns, the hospitalization rate for RSV is 16 times higher than that for the flu, and the mortality rate in newborns is five times higher.​

Pediatric Care Starting at the Fetal Stage

Because newborns have underdeveloped immune systems, they cannot produce sufficient antibodies on their own to combat aggressive respiratory viruses. To counter this vulnerability, Huang advocates for a proactive approach: pediatric healthcare must begin before the child is even born.

The government's ongoing "Healthy Taiwan" initiative has formally incorporated maternal protection as a key component of its public health strategy. Huang urged expectant mothers to discuss prenatal vaccination plans with their physicians during routine checkups. When a mother is vaccinated during pregnancy, her immune system generates protective antibodies that are transferred to the fetus via the placenta, equipping the baby with vital protection ahead of birth.

The 'Herd Immunity' Strategy at Home

While maternal vaccination is a powerful tool, Huang cautioned that it does not guarantee absolute protection for every individual.

For expectant mothers with specific health conditions or those who have serious concerns about receiving the vaccine, Huang recommended adopting a household "herd immunity" strategy. By ensuring that family members and close contacts of the pregnant woman are vaccinated, families can drastically reduce the risk of viral transmission in the newborn's immediate environment—creating an indirect, protective shield around both the mother and the infant. （Related： Israel’s Nuclear Ambiguity: How a Cold War Improvisation Became Decades-Long Strategic Doctrine ｜ Latest ）
