Flu Vaccination Service – FAQs

This page contains the answers to Frequently Asked Questions (FAQs) on the Flu Vaccination Service.

1. What are the benefits of flu vaccination?

The flu vaccine is an important way to reduce your risk of becoming seriously unwell with seasonal flu. It can lower the risk of complications and hospitalisation, particularly for people who are more vulnerable to severe flu. Vaccination also helps reduce the chance of passing flu to people who may be at greater risk. Hollowood Chemists provides seasonal flu vaccination services across its pharmacy network, with appointments available during the flu season.

2. Does a flu vaccine increase your risk of getting COVID-19?

No. The flu vaccine does not increase your risk of getting COVID-19. Flu and COVID-19 are caused by different viruses, and the flu vaccine is designed to protect against influenza rather than coronavirus. If you are eligible for both vaccinations, you may be able to receive them during the same appointment.

3. Is it safe to have the flu vaccine at the same time as a COVID-19 vaccine?

Yes. Flu and COVID-19 vaccines can be given at the same appointment when clinically appropriate. If they are not given together, there is no required interval between the two vaccinations. Your healthcare professional will advise you based on your individual circumstances.

4. How do flu vaccines work?

Flu vaccines prepare your immune system to recognise and respond to influenza viruses. The injected flu vaccines used for adults contain inactivated virus components and no live flu components and therefore, cannot cause flu. Protection develops after vaccination rather than immediately, so getting vaccinated before flu becomes widespread provides an opportunity for your immune system to build protection. It usually takes around two weeks for your immune system to develop protection following vaccination.

5. Who should not be vaccinated?

Most people can safely receive a flu vaccine. However, the most appropriate vaccine depends on factors including your age, medical history, allergies and whether you are pregnant. Tell your pharmacist or other healthcare professional if you have previously had a severe allergic reaction to a flu vaccine or any of its ingredients, or if you are currently unwell with a high temperature. Some flu vaccines have additional contraindications or precautions, so your healthcare professional will check which vaccine is suitable before vaccination.

6. Is flu vaccine safe for people who are pregnant?

Yes. Flu vaccination is recommended during pregnancy and can be given at any stage of pregnancy. Pregnancy can increase the risk of serious complications from flu, so vaccination helps protect both the pregnant woman and their baby. Some protection can also be passed to the baby through maternal antibodies, helping provide protection during the first few months after birth.

7. When should I get vaccinated?

For the 2026–27 season, pregnant women and eligible children can receive their flu vaccination from 1 September 2026. Most eligible adults can receive their vaccination from 1 October 2026. The later start for most adults is intentional, helping provide better protection during the period when flu is most likely to circulate. Most eligible people should ideally be vaccinated by the end of November, although vaccination continues later in the season for those who have not yet received it.

8. Why do I need a flu vaccine every year?

You need a flu vaccine each year because influenza viruses change over time, meaning the vaccine composition is updated to target the strains expected to circulate. Protection from vaccination also decreases over time. Having last year’s flu jab does not mean you will have the same level of protection during the following flu season.

9. Does flu vaccine work right away?

No. Your immune system needs time to develop protection after vaccination. It generally takes around two weeks for protection to develop. This is why getting vaccinated when offered, before flu becomes widespread, is recommended.

10. Can I get seasonal flu even though I got a flu vaccine this year?

Yes. The flu vaccine does not provide 100% protection, and its effectiveness can vary depending on factors such as the influenza strains circulating during the season and the individual receiving the vaccine. However, vaccination can reduce your risk of serious illness and complications if you do develop flu.

11. What protection does a flu vaccine provide if I do get sick with flu?

Vaccination reduces the risk of serious flu and flu-related complications. No vaccine provides complete protection, so it is still possible to develop influenza after vaccination.

If you develop flu after vaccination, the vaccine may still reduce the severity of illness and lower the risk of serious complications. This is particularly important for people who are more vulnerable to complications from influenza. Vaccination therefore remains worthwhile even though it cannot guarantee that you will not catch the flu.

12. Are there any vaccine side effects?

Most side effects from the flu vaccine are mild and short-lived. You may experience soreness, redness, or swelling around the injection site, or temporary symptoms such as a mild temperature or aching muscles. Injected flu vaccines do not contain live influenza virus and cannot give you flu. If you experience a serious or unusual reaction after vaccination, seek appropriate medical advice. Serious allergic reactions are very rare.

13. How do I get my flu vaccine?

You can arrange a flu vaccination through an eligible NHS provider or choose a private vaccination service where available. Hollowood Chemists offers seasonal flu vaccinations across its pharmacy network, (including St Helens, Wigan, Bolton, Trafford, Northwich, Crewe and Staffordshire), locations across North West England, and surrounding areas. The pharmacy team can explain the available service, check your eligibility, and advise on the appropriate vaccination option.
