The findings of this study suggest that the use of heterologous ChAdOx1 nCoV-19 and mRNA prime-boost vaccination is an effective alternative to increase population immunity against Covid-19, including against the Delta variant which dominated the confirmed cases during the study period. Background: Use of heterologous prime-boost COVID-19 vaccine schedules could facilitate mass COVID-19 immunisation. Background: Use of heterologous prime-boost COVID-19 vaccine schedules could facilitate mass COVID-19 immunisation. A new study supports the hypothesis that heterologous vaccination can provide an increased immune response against virus infection, supporting several other studies that have indicated similar events. This WHO recommendation pertains to heterologous primary and heterologous vaccine boosting for 2nd, 3rd, and 4th doses. Background: Use of heterologous prime-boost COVID-19 vaccine schedules could facilitate mass COVID-19 immunisation, however we have previously reported that heterologous schedules incorporating an adenoviral-vectored vaccine (ChAd, Vaxzevria, Astrazeneca) and an mRNA vaccine (BNT, Comirnaty, Pfizer) at a 4-week interval are more … The eligible populations and dosing intervals for the heterologous (“mix and match”) booster dose are the same as those authorized for a booster dose of the vaccine used for primary vaccination. Vaccination A new study supports the hypothesis that heterologous vaccination can provide an increased immune response against virus infection, supporting several other studies that have indicated similar events. A single booster dose of the Moderna COVID-19 Vaccine (0.25 mL) may be administered as a heterologous booster dose following completion of primary vaccination with another authorized or approved COVID-19 vaccine. Clover Biopharmaceuticals, Ltd., a global clinical-stage biotechnology company developing novel vaccines and biologic therapeutic candidates, announced that an investigator-led, Phase 2 trial initiated to evaluate the immunogenicity and safety of heterologous and homologous COVID-19 booster vaccines. These findings could have important implications for vaccination strategies … These findings could have important implications for vaccination strategies … heterologous vaccination series are comparable to those presented here below. Furthermore, the cellular and humoral responses of the two heterologous vaccine schedules at 28 days after the boost dose are no lower than those of the ChAd/ChAd schedule, which has shown to be highly effective in preventing severe COVID-19 disease, and no safety concerns were raised. Evidence from studies on heterologous vaccination suggests that the combination of viral vector vaccines and mRNA vaccines produces good levels of antibodies against the COVID-19 virus (SARS-CoV-2) and a higher T-cell response than using the same vaccine (homologous vaccination) whether in a primary or booster regimen. Several types of vaccines developed using different platforms have been authorized, but the immunogenicity and reactogenicity of heterologous prime-boost vaccination with different … Heterologous prime-boost settings with a protein vaccine and the viral vector vesicular stomatitis virus, both expressing tumor-associated antigens (KISIMA-TAA and VSV-GP-TAA), have been previously shown to generate potent antitumor immunity.

Heterologous (Mix-and-Match) Boosters. Com-COV (ISRCTN 69254139) is a UK multi-centre, participant-masked, randomised heterologous prime-boost COVID-19 vaccination study comparing all four prime-boost permutations of the ChAd and BNT vaccines both at 28-day and 84-day prime-boost intervals. Heterologous prime-boost settings with a protein vaccine and the viral vector vesicular stomatitis virus, both expressing tumor-associated antigens (KISIMA-TAA and VSV-GP-TAA), have been previously shown to generate potent antitumor immunity.

Furthermore, the cellular and humoral responses of the two heterologous vaccine schedules at 28 days after the boost dose are no lower than those of the ChAd/ChAd schedule, which has shown to be highly effective in preventing severe COVID-19 disease, and no safety concerns were raised. Heterologous prime-boost COVID-19 vaccination might be useful in responding to these challenges. Among the groups recommended by CDC to receive booster vaccination after a Pfizer-BioNTech, Moderna, or Janssen COVID-19 vaccine primary series, a single booster dose of any of the currently authorized or approved COVID-19 vaccines may be provided as a heterologous booster dose for those persons 18 years and older. Evidence from studies on heterologous vaccination suggests that the combination of viral vector vaccines and mRNA vaccines produces good levels of antibodies against the COVID-19 virus (SARS-CoV-2) and a higher T-cell response than using the same vaccine (homologous vaccination) whether in a primary or booster regimen.

Maharashtra received 963,000 doses of Covishield and 20,000 doses of Covaxin. Many national immunisation advisory groups implemented this strategy on a pragmatic basis following ChAd-related vaccine-induced thrombocytopenia and thrombosis events before evidence had accrued. In conclusion, heterologous vaccination regimens against COVID-19 provide an opportunity to speed up vaccination campaigns worldwide, maximising their impact on the control of the pandemic.
