Food and Drug Administration has focused its response for immunity against the fast spreading Omicron variant only on BA.4/5-adapted shots. The preliminary data on Thursday also showed that, in the age group of adults older than 55, the new bivalent shot triggered a better neutralizing antibody response against the Omicron BA.4/5 subvariant than the established shot based on the initial form of the virus.

In a joint statement on Thursday, the companies said data from a trial in adult patients showed the booster dose led to a substantial increase in neutralizing antibody levels against the BA.4/BA.5 variants after one week.

Similar applications are also planned for submission with regulatory authorities around the world in the coming weeks, the companies said in a statement. The booster has already been granted EUA by the FDA for ages 12 years and older. The authorisation is supported by safety and immunogenicity data from the Pfizer/BioNTech 30µg Omicron BA.1 adapted bivalent vaccine, as well as pre-clinical data which demonstrated a booster dose of the Pfizer/BioNTech Omicron BA.4/BA.5-adapted bivalent vaccine generated a ‘strong neutralising antibody response’ against Omicron BA.1, BA.2 and BA.4/BA.5 variants, as well as the original wild-type strain. The companies have also submitted an application to the European Medicines Agency (EMA) requesting a variation of the companies’ marketing authorisation in the EU to include a 10µg booster dose of Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine in this age group. The bivalent vaccine contains mRNA encoding the original SARS-CoV-2 spike protein – present in the original Pfizer/BioNTech COVID-19 vaccine – together with mRNA encoding the spike protein of the Omicron BA.4/BA.5 subvariants. Pfizer and BioNTech have been granted Emergency Use Authorisation (EUA) from the US Food and Drug Administration (FDA) for a 10µg booster dose of their Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine in children aged five to 11 years.

When comparing responses in individuals older than 55 years of age who received either the bivalent vaccine, or the original vaccine, a 30-µg booster dose of the Original Pfizer-BioNTech COVID-19 Vaccine (also referred to as BNT162b2 Wild Type) elicited more limited increases in the neutralizing antibody response against the Omicron BA.4/BA.5 variants.

Additional data measuring responses at one-month post-administration of the Omicron BA.4/BA.5 bivalent vaccine booster are expected in the coming weeks. “The current dominance of BA.4/BA.5 and related sublineages, underscores the importance of our data and science-based approach to develop a vaccine which is adapted to these prevalent strains of the virus and make it available in a timely manner.” A 30-µg booster dose of the Omicron BA.4/BA.5-adapted bivalent vaccine demonstrated a substantial increase in the Omicron BA.4/BA.5 neutralizing antibody response above pre-booster levels based on sera taken 7 days after administration, with similar responses seen across individuals aged 18 to 55 years of age and those older than 55 years of age (40 participants in each age group).

Additionally, pre-clinical data showed a booster dose of the 30-µg BA.4/BA.5-adapted bivalent vaccine generated a strong neutralizing antibody response against the Omicron BA.1, BA.2, BA.4 and BA.5 subvariants, as well as the original virus.

The FDA has authorized Pfizer's boosters without direct human data on how they perform against the omicron BA.5 subvariant.

The agency relied instead on human data from a similar shot developed by Pfizer against the original version of omicron, called BA.1, as well as data from animal studies that directly looked at how the shots perform against BA.5. The Food and Drug Administration authorized the omicron shots without direct human data on how they perform against omicron BA.5, which is causing most infections in the U.S. The first generation shots were developed only against the first strain of the virus. Pfizer and BioNTech said they will release more immune response data on the shots in the coming weeks. The participants who received the first generation vaccine saw a limited increase in antibodies against BA.5, according to the companies. Both age groups saw a substantial increase in antibodies that block the BA.5 subvariant from invading human cells, according to the companies.

Accenture, in partnership with Disability: IN and The American Association of People with Disabilities. He’s seen the benefits, first hand, with Michael and his work. Studies show that the benefits of a diverse workforce ripple through the company, and the greater community. For a healthcare company like Pfizer, there’s another reason to prioritize diversity: “Everything we do is about patients and their families,” says Rady. “People with disabilities are underemployed and underrepresented in workforces for lots of different reasons,” he says. Researchers at Accenture analyzed 140 companies and found that about one-third of those companies (45) excelled in areas related to disability and inclusion.2 Those companies also achieved 30% higher economic profit margins over a four-year period and were twice as likely to outperform the others in shareholder returns. “It gives you a purpose.” Through hiring pilot programs at 10 sites in the U.S., Europe, and Asia-Pacific regions, 60 individuals with disabilities have begun work. Through a global summer worker program, Pfizer collaborated with partners to identify student candidates with disabilities in an effort to support their path toward future employment. Rady's experience as a parent of a child living with an intellectual disability shifted his world view. In the United States, he stabilized with medical treatment. As he grew older, it was clear that he struggled with learning.

The study was relatively small, with only 40 participants in each age group of 18 to 55 and older than 55 years old. The FDA’s initial decision was supported by data from clinical trials run by the company of an earlier booster containing messenger RNA for both the original coronavirus strain and the BA.1 omicron variant.

Pfizer and BioNTech said their bivalent booster produced more antibodies against the targeted Omicron strains than earlier versions of their vaccine.

In the U.S., Pfizer and BioNTech plan to release additional data on the COVID-19 shots in the coming weeks to measure immune responses one month after administration of the new bivalent booster, which also targets the original coronavirus strain. The older cohort demonstrated a weaker antibody response against BA.4 and BA.5 compared with the younger cohort, the companies said. “These early data suggest that our bivalent vaccine is anticipated to provide better protection against currently circulating variants than the original vaccine, and potentially help to curb future surges in cases this winter.” The BA.5 subvariant that swept across the globe this summer still dominates, accounting for some four-fifths of the samples that are genetically sequenced and identified.
