Mercury Drug Flu Vaccine Price 2026: Flu Shot, Pneumonia & How It Works
Quick Answer: Mercury Drug does not publish an official vaccine price list. The last publicly reported price for a flu shot at Mercury Drug was ₱850, with pneumonia vaccines starting at ₱2,360 (GMA News, February 2025). Prices can change by season, brand, and branch, so confirm at the store. The vaccine administration itself is free, the service is for adults 18 and older, and you need a doctor's prescription issued within the past week. If you don't have one, select branches have onsite doctors who can screen you and write it. Senior citizens can often get a free flu shot through DOH and LGU drives instead.

How much is a flu shot at Mercury Drug?
| Vaccine | Last reported price at Mercury Drug |
|---|---|
| Flu (influenza) shot | ₱850 |
| Pneumonia (pneumococcal) vaccine | from ₱2,360 |
These figures come from a GMA News roundup of drugstore vaccine prices published in February 2025. Mercury Drug has not published a 2026 price list, and we found no newer official figure. Treat ₱850 as a reference point, not a quote, and ask the branch for the current price and brand before you go.
Mercury Drug also carries other adult vaccines at select branches. Which ones are in stock varies, so call the branch first if you need something other than a flu or pneumonia shot.
How does Mercury Drug's vaccination service work?
In April 2026, during World Immunization Week, Mercury Drug and vaccine advocates including the Philippine Foundation for Vaccination launched a nationwide campaign to get more adults vaccinated at pharmacies. Here is how Mercury Drug's in-store service works, as described at that launch:
- Adults only. In-store vaccination is for people 18 and older. Children's vaccines go through a pediatrician or health center.
- Bring a prescription. Vaccines are prescription medicines, so you need a doctor's prescription issued within the past week.
- No prescription? See the onsite doctor. Select branches have doctors who screen you and issue the prescription on the spot if you're fit to be vaccinated.
- Pay for the vaccine only. Mercury Drug says administration is free.
Not every branch offers vaccination. Check with your nearest store before going, and bring a valid ID.
How do Mercury Drug's prices compare with other drugstores?
The same February 2025 GMA News roundup listed these prices:
| Provider | Flu shot | Pneumonia vaccine |
|---|---|---|
| Mercury Drug | ₱850 | from ₱2,360 |
| Watsons | ₱850 | ₱2,370 or ₱3,850 |
| Southstar Drug | ₱850 | ₱2,360 – ₱3,995 |
| Hi-Precision Diagnostics | ₱1,450 | ₱3,846 or ₱5,550 |
| Kindred | from ₱1,500 | from ₱3,200 |
The three drugstore chains were priced the same for a flu shot. Clinics and diagnostic centers cost more. Watsons vaccinates by appointment, and Southstar asks you to pay at the branch before your schedule. For prices across clinics and hospitals, see our flu vaccine cost guide.
Where can you get a free flu shot?
- Senior citizens: under the Expanded Senior Citizens Act (RA 9994), the DOH provides free flu and pneumococcal vaccines to indigent senior citizens. For 2026, the DOH said it would procure about 6.9 million flu vaccine doses, with seniors and health workers as priority groups.
- LGU vaccination drives: cities run their own senior flu drives. Manila and the DOH launched one in Baseco on October 30, 2026, with more doses promised for other Manila communities. Ask your barangay health center or the Office of the Senior Citizens Affairs (OSCA) when your area's schedule is.
- Health centers: your local health center can tell you whether it has free flu vaccine stock and who qualifies.
For other vaccines and what they cost, see our vaccine cost guide.
When should you get your flu shot?
The flu vaccine is recommended once a year, because the circulating strains change and protection fades. In the Philippines, flu cases usually rise during the rainy season, so many people get their shot before or early in it. If you missed that window, getting vaccinated later still helps.
Seniors, people with heart or lung disease, diabetes, or weakened immunity, and pregnant women get the most benefit. A Daily Tribune report in April 2026 cited data showing only 36.3% of Filipinos aged 60 and older are vaccinated against flu.
