Fact Check: CRISPR Therapy ‘Erases’ HIV from Cells — But No Cure Yet

Article arrow_drop_down

A viral Facebook post with over 350,000 likes and 75,000 shares claims that scientists have developed a CRISPR-based therapy that removes HIV DNA from human cells and prevents the virus from returning.

Fact Check
This claim is misleading. While CRISPR research has made progress in laboratory experiments, no therapy has yet been proven to permanently remove HIV from the human body or to guarantee that the virus will not return.

What the Science Says

  • Laboratory Research:
    In 2024, researchers at Amsterdam University Medical Centre used CRISPR-Cas9 with two guide RNAs to cut HIV DNA out of CD4+ T cells in lab dishes. In those treated cells, the virus did not replicate immediately. However, this experiment was conducted outside the human body and does not reflect the complexity of HIV in living patients.
  • Human Trials:
    The most advanced CRISPR therapy for HIV is EBT-101, developed by Excision BioTherapeutics, now in Phase 1/2 trials in the United States. Results so far show the treatment is generally safe. But when participants stopped their regular antiretroviral therapy (ART), the virus returned in all of them. One participant stayed virus-free longer than usual, but the suppression was temporary.

Why a Cure Remains Elusive

Experts identify several barriers before CRISPR could realistically cure HIV:

  • Latent reservoirs: HIV hides in dormant cells that CRISPR cannot yet fully reach. These reservoirs can restart infection.
  • Delivery challenges: Getting CRISPR safely into the right cells across the body is still a major technical obstacle.
  • Viral diversity: HIV mutates quickly. CRISPR therapies that work on one viral strain may fail against others.

Verdict: Misleading

CRISPR has shown real promise in HIV research, and laboratory studies prove it can remove viral DNA from cells. Early human trials confirm the approach is safe, but no clinical evidence shows a cure or permanent prevention of viral rebound.

Conclusion:
The claim that HIV has been permanently erased from human cells is false. More research, better delivery systems, and larger clinical trials are required before CRISPR can be considered a cure for HIV.

Shank Comics claims Bovi Basketmouth are richer than Asake Wizkid

Skit maker and streamer Shank Comics says leading Nigerian comedians like Bovi Ugboma and Basketmouth are wealthier than some of the country’s biggest music stars, including Asake and Wizkid . Speaking during a recent livestream, Shank argued that comedy brings in strong long term income and that many comedians quietly build wealth while living modest lifestyles . He claimed that unlike some popular musicians, comedians often avoid extravagant spending on luxury cars and instead focus on safety, stability and long term financial security . Using Bovi as an example, Shank said the comedian is content driving a regular Lexus and has little interest in buying Ferraris, Lamborghinis or other flashy cars that some artistes are known for . He insisted that Bovi and Basketmouth are richer than stars such as Asake and Wizkid, but that their low key approach to […]

Seun Kuti urges jailing of pastors who stage fake miracles

Afrobeat singer Seun Kuti has called on the federal government to introduce strict laws against pastors who claim to perform fake miracles . In a video shared online, he urged the authorities to regulate miracle claims by requiring that they be verified and confirmed by medical experts . Kuti suggested that institutions such as Lagos University Teaching Hospital should be involved in checking whether any alleged miracles are genuine . He argued that supposed miracles must be repeatable and demonstrable under medical supervision before they can be accepted as real . To illustrate his point, he said a true miracle would include restoring full sight to a person who has no eyeballs at all, not just someone who has been blind for many years . Kuti said anyone who claims to perform miracles should be ready to repeat them for […]

Remi Surutu says Tinubu not to blame for fuel price hikes

Veteran actress Remi Surutu has defended President Bola Tinubu’s administration over the recent surge in fuel prices, saying the hikes are driven by global forces and not by the president or his government . Surutu spoke at the launch of EKO57, a support group created to mobilise backing for Tinubu’s second term bid, where she argued that decisions by world leaders largely determine petrol prices worldwide . She recalled confronting someone who blamed Tinubu for the fuel hike, insisting that the president is not responsible for the rise in petrol costs and that fuel pricing is influenced by international actors and market dynamics . According to her, many Nigerians wrongly assume that Tinubu controls fuel prices, whereas the increases reflect wider global economic and political developments beyond the direct control of the Nigerian government . Surutu reaffirmed her long standing […]

Zelensky warns of missile shortage amid conflicts

Ukrainian President Volodymyr Zelensky has warned that his country could soon face a shortage of key missiles due to the ongoing conflict in the Middle East, which is diverting military resources away from Ukraine. In an interview with BBC News, Zelensky said the escalation involving United States, Israel and Iran risks weakening Ukraine’s defence efforts. According to him, Russian President Vladimir Putin stands to benefit from a prolonged conflict in the Middle East, as it shifts global attention and resources away from Kyiv. Zelensky expressed concern that peace negotiations with Russia are being delayed, attributing the slowdown largely to the unfolding crisis in Iran. He also noted that rising global energy prices—driven by regional instability—are working in Moscow’s favour while putting additional pressure on Ukraine. A major issue highlighted by the Ukrainian leader is the potential shortage of air defence […]

Iran faces uncertainty after Larijani killing

The death of Ali Larijani, Iran’s senior security official, in an Israeli air strike marks a major turning point for the country’s leadership at a highly sensitive time. Although not a military commander, he played a decisive role in shaping Iran’s strategic direction on security, diplomacy, and conflict. As secretary of the Supreme National Security Council, Larijani was deeply involved in key decisions regarding Iran’s stance toward both United States and Israel. His influence extended across the political system, making him one of the most important figures behind the country’s policy choices. Following the killing of Supreme Leader Ali Khamenei in late February, Larijani adopted a firm position, indicating that Iran was prepared to sustain a prolonged conflict. His own death now adds to a series of targeted strikes that have eliminated several high-ranking officials and commanders in recent weeks, […]

Cuba hit by massive nationwide blackout

Millions of residents in Cuba were left without electricity after the country’s national power grid suffered a major collapse on Monday, according to the state operator UNE. The outage affected most parts of the island, marking another serious disruption in an ongoing energy crisis. Authorities said efforts are underway to gradually restore power across provinces and major cities, although the process remains slow and unstable. This latest blackout adds to a series of nationwide outages that have become increasingly frequent in recent years. The situation is largely driven by persistent fuel shortages. The country depends heavily on imported oil to generate electricity, but supplies have sharply declined. Previously, Venezuela provided a significant share of Cuba’s fuel needs, estimated at around half of total consumption. However, those shipments have stopped, worsening the crisis. Pressure has also intensified from the United States, […]
