Background: Despite the likely association between coronavirus 2019 (COVID-19) mRNA vaccines and cases of myocarditis/pericarditis, the benefit-risk assessment by the Centers for Disease Control (CDC) still showed a favorable balance for the primary series of COVID-19 mRNA vaccinations. Since August 2021, a full-scale booster vaccination in certain recipients has been recommended. Great concerns about whether the COVID-19 mRNA booster vaccination could increase the risks of myocarditis/pericarditis have been raised since then. The present study aimed to compare the incidence rates and risks of myocarditis/pericarditis between booster and primary vaccination programs.
Results: A total of 2,588 reports of myocarditis/pericarditis were identified after administration of primary-series COVID-19 mRNA vaccination and 269 after the booster dose program during the study period. The incidence of myocarditis/pericarditis following booster COVID-19 mRNA vaccination was lower than that of primary series. The results showed significantly high reporting of myocarditis/pericarditis following the administration of primary COVID-19 mRNA vaccination, whereas the disproportional level was lower in the booster-dose vaccination.
Conclusion: This study found that the booster dose of COVID-19 mRNA vaccination when compared with primary series course did not lead to an increase in the risks of myocarditis/pericarditis.
As we age, our immune response capability becomes reduced, which in turn contributes to more infections and more cancer. As life expectancy in developed countries has increased, so too has the incidence of age-related conditions.
While some people age healthily, the conclusion of many studies is that, compared with younger people, the elderly are more likely to contract infectious diseases and, even more importantly, more likely to die from them. Respiratory infections, including, influenza, the COVID-19 virus and particularly pneumonia are a leading cause of death in people over 65 worldwide. No one knows for sure why this happens, but some scientists observe that this increased risk correlates with a decrease in T cells, possibly from the thymus atrophying with age and producing fewer T cells to fight off infection. Whether this decrease in thymus function explains the drop in T cells or whether other changes play a role is not fully understood. Others are interested in whether the bone marrow becomes less efficient at producing the stem cells that give rise to the cells of the immune system.
Almost every mother has said it: "Wear a jacket or you'll catch a cold!" Is she right? Probably not, exposure to moderate cold temperatures doesn't increase your susceptibility to infection. There are two reasons why winter is "cold and flu season." In the winter, people spend more time indoors, in closer contact with other people who can pass on their germs. Also the influenza virus stays airborne longer when air is cold and less humid.

Data continue to show the importance of vaccination and booster doses to protect individuals both from infection and severe outcomes of COVID-19. For adults and adolescents eligible for a first booster dose, these shots are safe and provide substantial benefit. During the recent Omicron surge, those who were boosted were 21-times less likely to die from COVID-19 compared to those who were unvaccinated, and 7-times less likely to be hospitalized. CDC continues to recommend that all eligible adults, adolescents, and children 5 and older be up to date on their COVID-19 vaccines, which includes getting an initial booster when eligible.
These updated recommendations acknowledge the increased risk of severe disease in certain populations including those who are elderly or over the age of 50 with multiple underlying conditions, along with the currently available data on vaccine and booster effectiveness.
Exercise is one of the most effective ways to prevent many lifestyle-related diseases. Not only that but it can also boost your testosterone levels. One 2015 study involving men with obesity found that increased physical activity was more beneficial than calorie restriction for increasing testosterone levels (11).
Additionally, a 2017 study involving 102 men with a vitamin D deficiency found that taking a vitamin D supplement increased testosterone levels and improved erectile dysfunction. However, more research is needed, as other studies yield conflicting results (29, 30, 31).
Interestingly, one study involving older men found that an increased sleep duration of up to 9.9 hours was associated with increased testosterone levels. Conversely, sleeping more than 9.9 hours was tied to lower testosterone levels (40).
The strategies in this section are effective for increasing car seat and booster seat use. They are recommended by The Guide to Community Preventive Services or the National Highway Traffic Safety Administration. Different strategies may require different resources for implementation or have different levels of impact. This information can help decision makers and community partners see gaps and identify the most effective strategies to encourage parents and caregivers to always buckle up their children.
Child restraint laws require children riding in vehicles to be buckled up in approved restraints such as car seats, booster seats, or seat belts that are appropriate for their age, weight, and height. These laws are effective for increasing restraint use and for reducing child deaths/injuries. Strengthening current laws with booster seat provisions that require children who have outgrown car seats to use booster seats until at least age 9 helps increase use and reduce crash injuries and deaths.
Short-term, high-visibility enforcement programs can enhance the effectiveness of child restraint laws. These programs are often similar to or conducted in conjunction with those used to increase seat belt use. Programs are most effective when advertised widely in the media.
Car seat/booster seat distribution plus education programs help parents and caregivers obtain new, unused car seats or booster seats and learn how to properly install and use them. These programs often include hands-on demonstrations, which can help increase proper installation and use.
Fact sheets are available for each state and the District of Columbia. They have national and state data on restraint use and occupant crash deaths, as well as an overview of proven strategies for increasing the use of seat belts, car seats, and booster seats.
For 27 individual supplements (24.8%), there was data showing an increase in T with supplementation. Eleven individual supplements (10.1%) had data showing a decrease in T with supplementation, and 20 individual supplements (18.3%) had data showing no change in T with supplementation. Given these findings, 15 individual supplements (13.8%) therefore had conflicting data regarding their effect on T. These data are summarized in Table 3.
Illustrating this, a 2017 case report described new-onset, bilateral pulmonary embolisms secondary to over-the-counter fenugreek-extract-containing T supplements [13]. In 2014, the FDA issued a general warning for the risk of venous blood clots associated with T product use [14]. While not specified in the FDA warning, this potential risk may extend to herbal T supplements as well. Another study looking at the effect of red clover on the quality of life, and sexual function in men found that this supplement did not change sexual or erectile function, and resulted in a significant increase in liver transaminases [15]. In short, these vitamin and herbal substances may not be as safe as the public perceives them to be.
For 24.8%, or 27 out of 109 individual supplements, there was data showing an increase in T with supplementation. However, for many of these (15 of the 27, or 55.5%) there was also conflicting data showing no change or a decrease in T with supplementation. Of concern, 10.1% of components had published data that found a decrease in T with supplementation. It is unclear why companies would include components in their supplements that have no evidence to support their use. However, it is even more concerning that some of these supplements may in fact decrease serum T.
Garlic is safe in regular amounts, but too much garlic (especially raw) may cause heartburn, an upset stomach, or increase your risk for bleeding if you use blood thinners. Avoid eating more garlic just for collagen purposes.
Although the Food and Drug Administration recently recommended a second COVID-19 vaccine booster dose for older Americans, the country has had to confront an ongoing struggle -- problems getting initial vaccination series, let alone first booster shots into arms.
Solutions to the issue of uptake are critical because they not only affect us now, but are a problem that we will likely have to confront for years to come as COVID becomes endemic in the population. This may mean more frequent boosters until we are able to develop an annual multiple-part immunization package, having a combined COVID and influenza vaccine, for instance.
First, the science clearly shows boosters are effective. Data released last month from the L.A. County Department of Public Health shows that individuals who were vaccinated but not yet boosted had six times the protection from a COVID-19 ICU admission compared to the unvaccinated. Yet, for individuals who had the booster, this protection increased to ninefold. This translates to a 50% increased risk of an ICU stay for those fully vaccinated yet without their booster compared to those who received their booster. The bottom line here is clear: booster doses offer critical additional life-saving protection from COVID.
