Inactivated Vaccines

Inactivated vaccines can trigger a strong immune reaction, but it is usually not as strong as the reaction that live attenuated vaccines can produce. Due to this, a person may need booster shots to ensure ongoing protection.

The COVID-19 vaccines that Sinovac, Sinopharm, and Bharat Biotech have developed are inactivated vaccines.

Other examples of inactivated vaccines include those against polio, hepatitis A, and rabies.

Scientists at the private Chinese company Sinovac developed an inactivated COVID-19 vaccine called CoronaVac, while Bharat Biotech and the Indian Council of Medical Research co-developed Covaxin.

OK Aluminum does appear to be bad!

ALL THREE VACCINES CONTAIN ALUMINUM HYDROXIDE. This substance serves as an adjuvant, a term that scientists use to describe chemical compounds that boost the effectiveness of a vaccine.

Covaxin has an additional adjuvant called a toll-like receptor (TLR) 7/8 agonist – Trusted Source, which also prompts a strong immune response.

All three COVID-19 vaccines require administration in two separate doses.

Neurological Adverse Events of Immunization: Experience With an Aluminum Adjuvanted Meningococcal B Outer Membrane Vesicle Vaccine

It now appears to be well established that vaccines with aluminum adjuvants in some individuals are the cause of the histologic lesion called ‘macrophagic myofasciitis’. It is difficult to say how common such lesions may be for two reasons.

The size of the lesions may be very small and are, therefore, not always caught by the biopsy. Also, it would be considered unethical to take biopsies from healthy people, therefore, the true prevalence of these lesions cannot be determined.

However, the relationship between these lesions and the clinical symptoms is still considered an unproven hypothesis.(35,36)
