In order to attract attention in the fall of 2022, a fourth dose of the Govt vaccine will be required.. This was stated by Stephen Bonsell, CEO of Moderna, one of the two manufacturers of the MRNA vaccine. After 2 doses of the normal vaccination course, the effectiveness of the booster dose is expected to decrease over the months. Goldman Sachs I’ll be surprised to get data in the coming weeks based on how well the “booster dose” has been well maintained over time.
Many countries, including Great Britain and South Korea, are already ordering a fourth-round vaccine. “I hope we need booster doses in the fall and after 2022,” he says, noting the need for annual boosters for the elderly and frail. “According to our beliefs, we said this virus will not go away and we have to live with it,” the CEO added.
The appearance of the Omigron variant in the scene may accelerate the transition from crisis intensity to local level. At the same time, Boncel points out, caution is needed: the latest variation has taken the scientific community by surprise and the situation is likely to recur. “It’s absolutely impossible to predict whether a new variant will come in a day, a week, 3 months. And whether it is worse in terms of the severity of the disease. You have to be careful.”
In December, Moderna released an initial study showing that a booster dose of 50 micrograms increases antibodies 37 times for the omigron variant. With a size of 100 micrograms, this is 83 times. Data collected by the UK Health Security Agency in Great Britain show that 20 weeks after the second Pfizer or Modern dose, the effectiveness of anti-infective symptoms caused by Omigran decreases by 10%. The same report states that coverage rises to 75% in 2 weeks after booster dose. However, performance begins to decline after 4 weeks. That is why the hypothesis of a fourth dose is confirmed according to Pansell. Pfizer CEO Albert Bourla recently noted the need for a fourth dose and proposed a shorter interval to deal with the effects of Omicron.
