WHO says blanket use of booster dose will only widen vaccine inequality, prolong pandemic
The World Health Organization (WHO) criticized the popular idea of a full booster dose of vaccines against the coronavirus disease (Covid-19), stating that adopting such a policy would widen the pre-existing vaccine inequality between the first world. And relatively poor countries. When talking about this issue, WHO Director-General Ghebreyesus said at a press conference on Wednesday that a comprehensive Covid-19 booster program may also prolong the pandemic, rather than end it, “by transferring [ of vaccine] Countries that already have a high level of vaccination coverage.” The head of the WHO said that this will give the coronavirus “more opportunities to spread and mutate,” which may expand the pandemic. In consultation with the Strategic Advisory Group of Experts on Immunization (SAGE) and its Covid-19 Vaccine Working Group, WHO concluded that the vast majority of people currently hospitalized and died of coronavirus disease are unvaccinated people, not Those who have received injections or boosters.
The WHO Director-General said at a press conference: “No country can accelerate its escape from the pandemic.”
In the interim statement on Covid-19 booster doses issued on December 22, WHO made it clear that the focus of immunization efforts must continue to be on reducing deaths and serious diseases and protecting the healthcare system. This is especially important in light of the emergence of the Omicron variant of the coronavirus, which is said to be highly contagious and capable of frequent mutations. The WHO statement reads: “Countries/regions with high vaccination rates have high vaccine coverage, but in certain countries or local environments where key populations have not yet received primary vaccination, due to increased demand And the supply is diverted, so the risk of vaccination will exacerbate the availability of vaccines.”
According to the UN agency, barriers to access and distribution have led to widespread inequality in vaccine supply, which can only be resolved through high coverage and commitments by countries to achieve global vaccination targets and help other countries in need.
Public health agency forecasts indicate that only in the second half of 2022 will there be enough vaccines around the world to widely use boosters in all adults, and in cases where they are widely needed. But until then, broad-based strengthening plans will only continue to widen the existing supply gap, WHO concluded.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine
Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.
When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.
While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress.

Why recovery is key for muscle growth
According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.
Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.
Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.
Role of overtraining syndrome and deload weeks
Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.
Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.
Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
