Machine learning models for Prediction of the need for future Covid-19 vaccine booster
About 4 million Virginia citizens are fully vaccinated against COVID-19. According to medical data from nations like Israel and the United Kingdom, all those people may require another shot in the…
Immunogenicity and Safety of Homologous and Heterologous Prime–Boost Immunization with COVID-19 Vaccine: Systematic Review and Meta-Analysis
- Biology, MedicineVaccines
It is suggested that now, only individuals primed with inactivated vaccines require a booster dose, and the administration of the booster dose effectively recalled specific immune responses to SARS-CoV-2 and increased antibody levels, especially in heterologous immunization.

Persistence of immune responses to the Sinopharm/BBIBP‐CorV vaccine
- MedicineImmunity, inflammation and disease
To determine the kinetics and persistence of immune responses following the Sinopharm/BBIBP‐CorV, immune responses in a cohort of Sri Lankan individuals are investigated.
Percentages of Vaccination Coverage Required to Establish Herd Immunity against SARS-CoV-2
It is found that high percentages of vaccination coverage and high levels of vaccination effectiveness are necessary to block the transmission of Omicron and other SARS-CoV-2 variants with greater infectious capacity.

Risk Factors and Incidence Rates of Covid-19 Breakthrough Infections in Vaccinated People in General Medicine Practice in Toledo (Spain)
- MedicineArchives of Family Medicine and General Practice
COVID-19 breakthrough infections in vaccinated people were rare, with higher rates in women and old people, and the Janssen vaccine posed a strong risk; however, the small numbers prevent definitive conclusions.

Safety and Efficacy of the BNT162b2 mRNA Covid-19 Vaccine through 6 Months
- MedicineThe New England journal of medicine
Through 6 months of follow-up and despite a gradual decline in vaccine efficacy, BNT162b2 had a favorable safety profile and was highly efficacious in preventing Covid-19.
Protection of BNT162b2 Vaccine Booster against Covid-19 in Israel
- MedicineThe New England journal of medicine
It is found that the rates of confirmed Covid-19 and severe illness were substantially lower among those who received a booster (third) dose of the BNT162b2 vaccine.
Durability analysis of the highly effective BNT162b2 vaccine against COVID-19
The odds of experiencing a non-COVID-19 hospitalization decreased with time since vaccination, suggesting a possible underestimation of waning protection by this approach due to confounding factors and providing reassurance that BNT162b2 continues to protect against symptomatic SARS-CoV-2 infection several months after full vaccination.

Waning immunity of the BNT162b2 vaccine: A nationwide study from Israel
Quantifying the effect of waning immunity on vaccine effectiveness is critical for policy makers worldwide facing the dilemma of administering booster vaccinations after six months after a mass vaccination campaign against coronavirus.
Waning of BNT162b2 Vaccine Protection against SARS-CoV-2 Infection in Qatar
BNT162b2-induced protection against infection appears to wane rapidly after its peak right after the second dose, but it persists at a robust level against hospitalization and death for at least six months following the seconddose.
mRNA Vaccination Induces Durable Immune Memory to SARS-CoV-2 with Continued Evolution to Variants of Concern
It is observed that boosting of pre-existing immunity with mRNA vaccination in SARS-CoV-2 recovered individuals primarily increased antibody responses in the short-term without significantly altering antibody decay rates or long-term B and T cell memory.
Durability of mRNA-1273 vaccine–induced antibodies against SARS-CoV-2 variants
- Biology, MedicineScience
Binding and functional antibodies against variants persisted in most subjects, albeit at low levels, for 6-months after the primary series of the mRNA-1273 vaccine, which complement ongoing studies to inform the potential need for additional boost vaccinations.
Rates of SARS-CoV-2 transmission and vaccination impact the fate of vaccine-resistant strains
- Political ScienceScientific reports
It is shown that a period of transmission reduction close to the end of the vaccination campaign can substantially reduce the probability of resistant strain establishment and suggest that policymakers and individuals should consider maintaining non-pharmaceutical interventions and transmission-reducing behaviours throughout the entire vaccination period.
