Vaccines Deemed Safe by Medical Professionals
In a resounding clarity, medical experts in Malaysia have confidently dismissed claims that past Covid-19 vaccinations are linked to chronic ailments. With the nation grappling with a rising crisis of non-communicable diseases like diabetes and hypertension, many citizens have begun attributing their health challenges to vaccines received years ago—shifting the blame from lifestyle choices.
Dr. Leong Hoe Nam, an infectious disease expert from Singapore's Mount Elizabeth Hospital, explained, "The side effects of the vaccine are usually felt right after the shot or within two to three weeks at most. Beyond that, there’s no evidence of any lasting impacts." He underscored ongoing vigilant monitoring for adverse effects, but noted, "Despite incentives for scientists to find any possible links, no connections have been established."
Claims of Long-Term Effects Debunked
Contributing to this discourse, Dr. Megat Mohamad Amirul Amzar Megat Hashim, a family medicine specialist, echoed these sentiments. He stated firmly that there is no evidence connecting Covid-19 vaccines with chronic conditions like heart disease or cancer. In fact, a recent study indicated that receiving three doses of the Covid-19 vaccine actually reduces the risk of heart attack and stroke.
Dr. Amirul elaborated on the biological unlikelihood of delayed side effects, emphasizing that serious adverse reactions are predominantly immediate and happen within minutes to weeks after vaccination.
Global Covid-19 Resurgence Raises Concerns
While Malaysia manages a relatively stable COVID-19 situation—with reported cases remaining below the national warning threshold—neighbouring countries like Singapore, Thailand, and Hong Kong are witnessing a surge in cases. Singapore recently reported a 28% increase, while Thailand's cases have doubled in a week, highlighting the virus's ongoing threat.
Quick Relief: Immediate Side Effects Identified
Addressing what individuals might expect right after vaccination, Dr. Leong shared, "Common immediate side effects include pain and swelling at the injection site, mild fever, and occasional fatigue. Rare cases of myocarditis have been observed, but these occur at a minimal rate of under 1 in 100,000."
Both doctors agree that serious complications are exceedingly rare and typically happen shortly after vaccination. Dr. Amirul reminded the public that most side effects are mild, self-limiting, and become manageable with fast medical intervention.
Inoculations Far Safer than Infection Risks
Both experts cautioned against downplaying the dangers of Covid-19 itself. They emphasized that the risks associated with contracting the virus significantly outweigh potential vaccine-related side effects. Dr. Hoe noted, "Natural infections pose a far greater risk—leading to more severe health issues than what vaccines might cause. Vaccinations aim to shift those risks into safer territory."
No Evidence of Long-Term Adverse Effects
Dr. Amirul pointed out the stability of mRNA vaccines, which have been subjected to extensive research for over a decade without any indication of long-term side effects. He reiterated that mRNA degrades quickly after achieving its immunological functions, making sustained negative impacts highly improbable.
Dr. Hoe added that as life progresses, various health issues naturally arise—often unrelated to vaccination. "Coincidences are frequent. Just because someone receives a vaccine and later faces health challenges doesn't mean one caused the other. To suggest such a connection would be misleading."
Vaccinations Continue to Evolve Against Variants
The World Health Organization recently reaffirmed the role of vaccinations in combating Covid-19 variants, highlighting ongoing research to enhance vaccine formulations as the virus evolves. They encourage continuous immunization as a primary public health approach against new strains.
In conclusion, experts from Malaysia firmly state that unfounded fears linking Covid-19 vaccinations to chronic ailments should be put to rest. Vaccines are essential in curbing disease spread and protecting public health as we navigate a world still affected by the Covid-19 pandemic.
