Health experts warned that flu-related hospital bills could reach up to P30,000 and said infections are likely to surge with the onset of the rainy season, urging families to get vaccinated early to avoid the steep financial burden.

“Flu is not a simple cold. Cases spike during the rainy season and are a serious threat, especially for older adults with chronic diseases like hypertension and diabetes,” Dr. Maria Cristina Ignacio-Alberto, a board member of the Philippine Foundation for Vaccination (PFV), said in a statement.

“These groups account for 70% of flu hospitalizations and 85% of flu-related deaths, often due to a lack of awareness and delayed diagnoses. That’s why being proactive with vaccination remains the most effective and cost-effective way to protect against severe illness,” she went on.

A single hospitalization due to flu can cost between P10,000 and P30,000, Alberto warned, with most families paying out of pocket.

“That’s a big blow to families with limited income and those who cannot afford to take time off work. This disruption adds another layer of stress for families but also creates a ripple effect on our economy,” she said.

Despite the clear risks, flu immunization coverage in the Philippines remains below optimal levels.

Alberto urged the public not to wait until infections spike before taking action.

“We can’t wait for flu season to peak before acting. Vaccination efforts must begin early to ensure more Filipinos are protected before infections surge,” she said.

She also encouraged Filipinos to speak with healthcare providers about other important vaccines beyond the annual flu shot.

“Vaccination should be a national priority. Through our IBA ang BAKUNADO campaign, we call on all sectors to work together in strengthening the healthcare system and improving vaccine access nationwide, helping build a healthier, more resilient country,” Teodoro Padilla, the executive director of PHAP, said.

Alberto underscored that expanding access to timely, affordable vaccination isn’t just about preventing illness, it’s about protecting household income, maintaining productivity, and easing pressure on the health system.

The PFV and PHAP both said protecting the public from flu and other vaccine-preventable illnesses must be treated as a shared responsibility, requiring action not only from government, but from communities, employers, and families alike.

“Vaccination is not only about health—it’s about survival and security for Filipino families,” Alberto said.
