Research Highlights Vaccine's Role in Reducing Long COVID Risk

Two large studies highlight the effectiveness of COVID-19 vaccines in reducing long COVID risk. A US study found the Pfizer-BioNTech vaccine significantly reduced long COVID in children and adolescents during both Delta and Omicron phases, with higher efficacy during Delta. A Japanese study showed that three or more vaccine doses reduced long COVID symptoms by 30% in women, particularly neurological symptoms, but not in men. The studies emphasize the vaccines' role in preventing infections, which in turn reduces long COVID risk.

2023 Nobel Prize Winners: Celebrating the Tenacious Force Behind the Covid Vaccine and mRNA Research

Katalin Karikó, a Hungarian-born biochemist, played a crucial role in the development of the Covid vaccine through her pioneering work on mRNA technology. Despite facing setbacks and skepticism, Karikó's perseverance and dedication led to breakthroughs that laid the foundation for the successful Pfizer-BioNTech vaccine. Her contributions to medical research have revolutionized the field and opened up new possibilities for future vaccines and treatments.

FDA Approves Updated COVID Vaccines to Boost Protection

The U.S. Food and Drug Administration (FDA) has authorized updated COVID-19 vaccines from Pfizer-BioNTech and Moderna that target the Omicron variant of the coronavirus. The vaccines are expected to be available for most people in the United States in the coming days. The FDA approval includes emergency use authorization for children ages 6 months through 11 years. Novavax's vaccine is still under review by the FDA, and the company expects authorization in the near term. The authorization follows a rise in cases and the emergence of new subvariants of the Omicron variant. The CDC is expected to endorse the new shots, paving the way for their rollout in September.

"Essential Facts on the Latest Covid Booster Shots"

The FDA has approved two new monovalent Covid-19 booster shots from Pfizer-BioNTech and Moderna, designed to protect against the XBB.1.5 variant and other concerning variants. The CDC is expected to provide guidance on eligibility soon, and the vaccines could be available within days. The new shots do not include protection against the original virus, which may help broaden protection against new variants. The cost of the shots will be negotiated by insurance companies and government payers, but they are expected to remain free for most people with insurance. The CDC is likely to authorize the new boosters for everyone 6 months and older, with a focus on high-risk individuals first. It is safe to get the Covid booster and flu shot at the same time.

COVID-19 Vaccine Showdown: Moderna Outperforms Pfizer-BioNTech for Seniors

A study conducted by researchers at Brown University compared the Moderna and Pfizer-BioNTech COVID-19 vaccines in over six million older adults and found that the Moderna vaccine was associated with slightly lower risks of certain adverse events, such as pulmonary embolism and thromboembolic events. The study highlights the importance of understanding real-world vaccine performance and recommends further research, including the evaluation of subsequent vaccinations and newly developed vaccines. While both vaccines were found to have low risks of adverse events, the findings suggest that the Moderna vaccine may have a slight edge over Pfizer-BioNTech for older adults.

Moderna's mRNA COVID Vax: Safest and Most Effective for Older Adults and Immunocompromised Patients

A study conducted by Brown University researchers found that the Moderna COVID-19 vaccine may be slightly safer for adults aged 66 and older compared to the Pfizer-BioNTech vaccine. Both vaccines were deemed safe and effective, but the study suggests that the Moderna vaccine may have a lower incidence of adverse events in this age group. The research aims to provide more guidance for older adults and those with increased frailty when making decisions about vaccination. It is important to note that both vaccines are significantly safer than not being vaccinated at all, and the study's findings can help inform vaccine choices for different age groups and populations.

COVID-19 vaccine updates and recommendations for all doses and demographics.

The FDA has recommended the use of bivalent Moderna and Pfizer-BioNTech COVID-19 vaccines for all doses administered to residents at least 6 months old, while monovalent COVID-19 vaccines are no longer recommended for use nationwide. The updated vaccines and boosters are bivalent, which means they are created with two strains of the virus and include the newer omicron variant strains. The CDC’s Advisory Committee on Immunization Practices supports the recommendations. Alternatives to mRNA COVID-19 vaccines are available, and the CDC’s recommendations for monovalent Novavax or Johnson & Johnson’s Janssen COVID-19 vaccines have not changed.

"Controversy Surrounds Florida Surgeon General's Alteration of Covid-19 Vaccine Safety Study"

Florida Surgeon General Joseph Ladapo personally altered a state-driven study about Covid-19 vaccines last year to suggest that some doses pose a significantly higher health risk for young men than had been established by the broader medical community. Ladapo’s changes presented the risks of cardiac death to be more severe than previous versions of the study. He later used the final document in October to bolster disputed claims that Pfizer-BioNTech and Moderna vaccines were dangerous to young men.

"COVID Booster Shots: Updates and Eligibility"

The U.S. Centers for Disease Control and Prevention has recommended an additional updated COVID-19 booster shot for seniors 65 and older as well as those who are immunocompromised. The updated booster was first introduced last September. Most people who have already gotten the updated bivalent booster are not eligible for another dose. However, those who haven’t gotten the first shot are free to roll up their sleeves. The CDC recommended that everyone 6 and older get the updated COVID-19 shot — regardless of whether they had completed their primary vaccination series.

FDA approves simplified use of bivalent COVID vaccines and additional booster for high-risk individuals.

The FDA has authorized changes to the emergency use authorizations of the Moderna and Pfizer-BioNTech COVID-19 bivalent mRNA vaccines to simplify the vaccination schedule for most individuals. The monovalent Moderna and Pfizer-BioNTech COVID-19 vaccines are no longer authorized for use in the United States. Available data show that almost all of the U.S. population 5 years of age and older now have antibodies as a result of either vaccination or infection against SARS-CoV-2. The use of bivalent COVID-19 vaccines for all doses administered to individuals 6 months of age and older is supported by the data.

COVID-19 Vaccines and Neurological Effects: New Case Report and Booster Study Findings

A case report has been published describing a patient who developed intracranial hemorrhage after receiving the Pfizer-BioNTech COVID-19 vaccine. The patient, who had a history of hypertension and was taking aspirin, presented with a severe headache and was found to have a subarachnoid hemorrhage. While the authors note that this is a rare event and the benefits of vaccination outweigh the risks, they suggest that individuals with a history of bleeding disorders or those taking anticoagulants should be monitored closely after vaccination.

FDA approves Pfizer's bivalent COVID-19 booster for young children.

The FDA has authorized a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine, Bivalent for children aged 6 months through 4 years who have completed their three-dose primary series with the monovalent Pfizer-BioNTech COVID-19 Vaccine at least two months ago. The bivalent vaccine includes an mRNA component corresponding to the original virus strain and the omicron variant BA.4 and BA.5 lineages. The authorization is supported by immune response and safety data from clinical studies and postmarketing safety data. Vaccination remains the best defense against severe COVID-19 outcomes, and eligible individuals are encouraged to ensure their vaccinations are up to date with a bivalent COVID-19 vaccine.
