About Flu Vaccines

What are flu vaccinations?

Flu Vaccinations are one of the simplest and most effective ways of protecting your health, productivity and peace of mind. Whether you are a private individual concerned about avoiding an unpleasant illness and its complications, looking for the best care for you and your family, or a company concerned about business continuity and the health and welfare of your staff, we have the practical experience and the specialist expertise to help you.

What strain will the 2020/ 2021 Quadrivalent flu vaccine protect against?

Every flu season there are different flu strains that circulate. Flu strains can mutate which is why the composition of flu vaccinations change every year.

In advance of each flu season, the World Health Organisation uses all available laboratory data from around the world to predict the likely predominating strains, and to direct vaccine manufacturers on the best choice of strains to include in their vaccines.

The Quadrivalent flu jab includes two types of A and two B strains.
During the 2020/2021 flu season the following strains included in the vaccinations are:

  1. A/Guangdong-Maonan/SWL1536/2019 (H1N1)pdm09-like virus or an A/Hawaii/70/2019 (H1N1)pdm09-like virus;
  2. A/Hong Kong/2671/2019 (H3N2)-like virus;
  3. B/Washington/02/2019 (B/Victoria lineage)-like virus; and
  4. B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.

How effective are flu vaccines?

Now that the Northern Hemisphere flu season has passed, we know the predominating strains in the UK were the second and fourth strains from the above list: the H3N2 and the B/Yamagata like B/Phuket strains.

The Quadrivalent vaccine has proved to be partially effective against the H3N2 strain, but highly effective against the 4th strain, which is caused approximately 60% of clinical cases. The number of cases that occurred in the UK approached “outbreak” levels, and certainly caused significant concern – which raised questions about whether the Quadrivalent vaccine should have been used more widely in the NHS and at a national level. As a result since 2019 flu season, Public Health England have made the following recommendations:

  • Quadrivalent vaccinations to be offered to 18 – 64-year-olds
  • Nasal spray quadrivalent vaccines offered to under 18’s
  • Adjuvanted trivalent for those aged 65 and over

Flu is unpredictable and it is impossible to know which strains will circulate each season and so we have to use our best judgement about which vaccines to offer. Vaccination still remains the best defence against flu. At the Fleet Street Clinic, we have consistently supported the use of the Quadrivalent vaccine, on the basis that it significantly increases the probability of good protection.

When do you have a flu vaccine?

The flu vaccine is normally given as early as possible in the autumn, and the protection lasts through the winter and beyond, though because of mutation, “drift”, and other changes in the circulating viral strains, new vaccines are generally needed each year.

What flu vaccine would you recommend?

Alongside Public Health England, to ensure you have the best level of protection available our recommendations for this year are as follows:

  • Quadrivalent vaccinations to be offered to 18 – 64-year-olds
  • Nasal spray quadrivalent vaccines offered to under 18’s
  • Adjuvanted trivalent for those aged 65 and over
  • Cell-based vaccines for those with severe egg/chicken protein allergies

The Fleet Street clinic has been at the forefront of recommending the 4-strain Quadrivalent flu vaccination to patients since its introduction to the market. Whether you are an individual or representing a corporate client or a parent seeking a flu vaccination for you and your family we are committed to offering you the broadest and best choice of flu vaccinations.
