GlaxoSmithKline's (LON:GSK) share price has risen quite dramatically since the beginning of the year with a 108.70 point gain (+7.35%). Although the share price has seen a decline in the last 5 days, down 2.16%, the news of GSK's 5 in 1 ABCWY meningococcal vaccine trial is currently under review by the US Food and Drug Administration (FDA). The pharmaceutical giant's commitment to simplify the vaccination process against invasive meningococcal disease is on the verge of a potential breakthrough.

The proposed vaccine has been formulated to offer protection against five serogroups of Neisseria meningitidis – A, B, C, W, and Y, which are responsible for the majority of meningococcal infections. Typically, immunisation against these varied strains would require multiple injections, a challenge that the new vaccine hopes to address.

The FDA's review comes on the heels of impressive clinical trials outcomes. GSK revealed that the vaccine met all primary endpoints in its pivotal phase III trial. This success in the advanced stage of trials suggests that the vaccine is not only efficacious but could also stand a strong chance of being recommended by health authorities upon its approval.


The broader implications of a successful 5-in-1 vaccine are considerable. Reducing the number of injections required for comprehensive meningococcal immunisation could greatly improve vaccination schedules, making the process more concise for healthcare providers and less daunting for individuals, especially adolescents who are at heightened risk for this infection.

Moreover, this potential advance in the vaccine landscape could play a pivotal role in increasing vaccination uptake. A simpler and more convenient immunisation approach is anticipated to improve coverage rates, thereby lowering the incidence of invasive meningococcal disease across the population.

GSK is now awaiting a critical decision from the FDA. All eyes are on the impending regulatory judgment which is expected to be announced by February 14, 2025. Public health stakeholders and the medical community at large anticipate this development with the hope that it will mark a significant step forward in infectious disease prevention and control.

Analysts view on GSK's Stock

On the 08/04/24 Barclays raised GSK's price target raised to 1,725 GBp from 1,575 GBp, which shows an positive sentiment on GSK's share price. Last month, on 04/03/24 Guggenheim upgraded GSK to Buy from Neutral with a 2,031 GBp price target. This was in relation to the launch of Arexvy which is for active immunisation for the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus in individuals 60 years of age and older.

Analysts are reacting positively to GSK's share price, and they seem to have month on month announcements of new medical advancements in the pharmaceuticals sector. They have a market cap of 65.68 billion and are undoubtedly one of the sector leaders. Investors have pegged GSK as “one to watch” in 2024 and the introduction of this multivalent vaccine could set a new standard for immunisation practices. GlaxoSmithKline stands at the forefront of this potentially transformative healthcare solution, underscoring the pharmaceutical industry's role in innovating for better global health outcomes.
